Audio Overview of Mainstream Music Inventory in 2016

　　　　In fact, I am very happy to write this inventory, and finally write about the audio, because I not only experienced the mobile phone scheme, but also listened to the eight mainstream HiFi music phones in 2016, and my ears were almost polished into golden ears. However, this issue will not tell you too much about the evaluation of sound quality, but will talk about the HiFi music phones that I think are the mainstream this year by way of comments, and then I will make a report on the HiFi mobile phone market next year.

　　　　In this issue of 2016 mainstream music mobile phone inventory, the author follows the following points:

1. Mobile phone brands are familiar to everyone.

2, with independent chip bonus.

　　　　In fact, these two points are also the characteristics of a music HiFi mobile phone. Big brands will have good technology research and development. In fact, the most important thing is the use of chips and sound tuning. You must know that some HiFi audio chips are completely customized for mobile phones, which requires the common optimization ability of chip manufacturers and mobile phone manufacturers; In addition to the chip, you need a Andhadhun. The author’s understanding of Andhadhun is to use relevant acoustic principles to optimize the chip and mobile phone lines (of course, this needs to be combined with architecture and line analysis) to make the sound more real and natural.

Figure Reference Table of Mobile Phone Release and HiFi Music Mobile Phone Release from 2013 to 2016

　　　　In fact, what makes the author very happy this year is that 85 mobile phones are music phones, and the music part was mentioned more or less at the time of release. This year, there are 835 mobile phone models on the market, accounting for 10.2%, which is still an increase compared with last year. In 2015, the number of released mobile phones was 815, of which 45 were music phones, accounting for 5.5%. In 2014, this number was still decreasing, with 900 mobile phones released, including 46 music mobile phones, accounting for 5.1%; In 2013, 863 mobile phones were released, including 28 music phones, accounting for 3.3%.

Figure HiFi music mobile phones accounted for the percentage of all mobile phones sold in that year.

　　　　From this point of view, manufacturers are constantly paying attention to the future development of music mobile phones. It is predicted that in 2017, HiFi music mobile phones will become an area that manufacturers will compete for, because there are constantly traditional HiFi chip manufacturers customizing chips for mobile phones. In fact, mobile phones that use HiFi chips alone can also be excavated from music mobile phones. This number is also constantly rising.

　　　　Therefore, in view of this inventory of music mobile phones, the author will be divided into two parts.Today, this part is called "Mobile Phone Playing HiFi 2016 Mainstream Music Mobile Phone Inventory", which is to let readers know about the release of music mobile phones from 2013 to 2016 first, and use charts to give readers a clear understanding. After that, I will give readers an inventory of the music mobile phones that I think are excellent this year, and have a simple understanding.

　　　　In the second part, I will put some very important parameter tests in the next topic, and I will use this part.Actual parameter sumActual hearing senseGive the reader a clear picture. The test platform will choose RMAA, which takes some time to adjust and prepare, and gives a more comprehensive and objective analysis combined with the sense of hearing.

　　　　If you want to be less laborious, you can read this simple inventory and have a general understanding of this year’s HiFi music mobile phone.

HiFi mobile phone pioneer　

vivo　　

　　A scheme that has been developed for more than two years is used: -Fi3.0 architecture. Dual ES9028, triple OPA1612, and independent decoding and amplification of left and right channels are adopted, with dual clock crystal oscillator and secondary power supply. Compared with the ES9018K2M (signal-to-noise ratio of 127dB, distortion rate of -120dB), which is jointly customized and developed by vivo and ESS, it has been widely used, and adopts QFN packaging method. ES9028Q2M, according to the official introduction of ESS, the signal-to-noise ratio of the chip is as high as 129dB, while the distortion rate is -120dB. The data can be said to be excellent.

　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　Introduction to ESS9028 (fromESSOfficial website)

　　　　At the same time, a dual channel is used in the mobile phone, one channel is ESS9028, and then the left and right channels are decoded separately through OPA1612. The advantage of this is that the crosstalk interference can be minimized and the overall parsing ability can be improved.

　Interpretation of sound quality chip (picture taken from vivo network)

Summary:

　　　　In fact, the most important sound of this mobile phone is the consistent feature of ES9028: outstanding resolution, relatively large thrust of sound in the mobile phone, and general headphones will be full, so there will be no big problems in this respect.

Classical sound first choice　

　　　　ZTE is the one I like very much, especially the front of the top version. The upper and lower materials of walnut can show a noble workmanship. In fact, the author has already evaluated the sound quality of this mobile phone before, and this time I just want to review it with readers. Of course, we must pay attention to the audio configuration of the mobile phone: AKM4490+AKM4961.

　　　　Let’s take a brief look at the chip promotion page of the chip manufacturer

Chip introduction (from ESS official)

　　　　AK4490EN is an ideal audio chip for mobile devices. It supports high bit rate input PCM 32BIT/768KHz source output, and also supports high-specification 11.2MHz DSD files.

Chip introduction (from ESS official)

　　　　AKM’s advanced DAC chip AK4490EN and top DSP series AK4961. K4961 further integrates ADC into the interior, in other words, it adopts independent ADC+ independent DAC+ independent amplifier, and has high-quality recording and sound playback processing ability in AK4961 chip, which can be applied to computers, mobile phones, voice recorders and other professional tools.

restore

　　　　In fact, the configuration of this mobile phone is also the mainstream flagship configuration: Xing uses a 2K resolution AMOLED screen, equipped with Qualcomm Snapdragon 820 quad-core processor, and built-in 4GB/6GB large memory +64GB/128GB storage space combination. It has a front camera with 8 megapixels+a rear camera with 20 megapixels.

Clean and powerful voice control　

　　　　For Meizu, there is no need to say too much about sound, because the audio is indeed a very experienced manufacturer, and Meizu Music Card is a classic product, which is very good in terms of workmanship and sound. For the flagship, Meizu is also very attentive to the sound quality, first of all, it is the exploration and application of sound quality chips: the CS43L36 decoding and amp integrated chip of CirrusLogic.

　　　Meizu adopts a CS43L36 decoding and amp integrated chip of CirrusLogic, which basically controls the audio parts involved.

Simple chip introduction (picture from CirrusLogic official website)

　　　　This chip is an integrated chip of decoding and amp that CirrusLogic specifically solves for mobile solutions. There is very little introduction on the official website, so we can only take the sense of hearing as a reference. Is the sound of the independent chip better or the integrated solution better?

Meizu official website Sound Quality Introduction Interface (Image from Meizu official website)

　　　　In terms of configuration, it is also the flagship level: Meizu uses a 5.2-inch 1080p screen with 2.5D cambered Corning Gorilla glass protection, and is equipped with MediaTek’s ten-core Helio X25. The processor adopts a 3-cluster architecture, based on ARM big.LITTLE, with a 20-nanometer process, and the highest frequency is 2.5GHz. Built-in memory combination of 4GB RAM+32GB/64GB ROM can smoothly run Flyme 5.6 based on Android 6.0 system, and has a built-in 2560mAh battery.

MEIZU

　Editor’s comment:

　　　　This mobile phone is very good with portable big ears, especially headphones with low impedance and low sensitivity. It can also be seen from the side that the thrust of this mobile phone is appropriate, even if the vocal performance is not exciting, it is a kind of voice that is a little warm and a little hoarse.

Excellent hammer l without mentioning sound quality　

　　　　I believe many friends are very interested in this year’s release. After all, this one can be said to be the main stream of the hammer mobile phone, especially the hammer and L. Especially from the configuration point of view, it is indeed the flagship mainstream level. In fact, the author is most concerned about the audio chip of the hammer mobile phone. As can be seen from the official website, this mobile phone uses chips that are very mainstream in the market and have excellent performance and parameters.

Parameter comparison between Smartisan and Smartisan L (quoted from the official website of Hammer)

　　　　CS4398 is the flagship decoding chip of Cirrus Logic, and its performance is excellent. It can also be found in the CD player with a price of more than 70,000 yuan. CS4398 is a decoding chip with a specification of 24Bit/192K Hz. It has a signal-to-noise ratio of more than 120 dB and a dynamic range, and the total harmonic distortion+noise is as low as 0.0005%. It adopts an advanced special multi-bit Delta-Sigma modulator and integrates mismatch noise shaping technology. (It seems to be very powerful) Although the price and index of cs4398 are not the highest and most expensive category of decoding chips, the sound of this sound quality chip is actually very special.

Smartisan series

Editor’s comment:

　　　　Although the specific parameters of this mobile phone were not put forward in detail at the press conference, it is very good in both the audio parameters and the actual listening sense. The single DAC chip not only improves the sound thickness, resolution, sound field and thrust compared with the mobile phone without a single DAC chip.

　See also ES9018K2M chip.　

　　　　This chip can be said that the author likes a chip very much. From the traditional computer to the terminal, almost all audio-related devices adopt ESS Technology’s chip technology, such as the recently popular Daao II HE1 and HiFiMAN 901 series, etc., and the chip technology of ESS Technology was adopted as early as possible, which is enough to show the importance attached by vivo mobile phones to audio.

The second generation of Daao uses the full version of ES9018 chip (quoted from Google).

　　　　Actually, for ESS, ESS Technology Inc. was founded in California in 1984, and its founders applied the scientific and technological inventions of audio reconstruction to electronic audio books and greeting cards. ESS then applied this audio technology to personal computers, successfully developed the first stereo single chip, and condensed the huge computer sound blaster card into a semiconductor chip, becoming the leader of audio chip technology for personal computers and notebook computers.

The mobile terminal adopts ES9018K2M chip (quoted from baike).

　　　　Today, ESS Technology Company has developed into an important manufacturer of semiconductor chips for multimedia, personal computers, consumer electronics and other products in the world. Besides computer audio chips, video technology (MPEG) and fax/Modem technology (Modem) of ESS provide customers with high-performance, advanced technology and reasonable price chips and supporting software solutions, which is one of the important pillars of ESS Company’s success.

　Plus

　　　　As a mobile version of ES9018, ES9018k2m perfectly solves the problem of huge power consumption, and has a dynamic range of 127dB DNR. The ESS audio chip has 127 dB, which can better show the details of music. The ultra-low distortion of -120dB THD+N can better restore the essence of music; The sampling rate reaches 192kHz/24bit, which will meet the performance level of the most demanding audio lovers. At the same time, it also supports a variety of lossless music such as DSD, APE and FLAC, so that you can enjoy higher quality music.

Editor’s comment:

　　　　This chip is mature, and it is very suitable to be placed on vivo X9 Plus. First of all, the sound is clean and the background is very black. At the same time, matching headphones can be described as "tiger balm", especially earplugs, which can get a good sense of hearing.

It has always been a custom chip.　

　　　　The biggest difference is the removal of the 3.5mm headphone jack. In fact, we still need to start from the initial disassembly. First of all, the author can find from the disassembly diagram that the previous 3.5mm headphone jack has been occupied by the TAPTIC Enging module and the home button. This module can bring a similar feel to the mechanical Home button when pressing the iPhone7. However, the impression of thinning the thickness of the fuselage did not appear, and I can only say that I was slightly disappointed.

From the disassembly diagram, we can see that TAPTIC ENGING in the new iPhone7 series occupies the position of 3.5mm headphones.

　　　　1MORE’s three-cell ring iron earphone Lightning digital version with iPhone7 simple listening introduction:

　　　　This earphone had the first generation, 1MORE three-cell ring iron earphone. This time, the plug was replaced by Lightning and the decoding chip was built in. What about it? First of all, the biggest feeling for the author is: the improvement of overall analytical power and clean background. The song "Never say never" can fully show the characteristics of this earphone: the vocal performance is clear, and Justin Bieber’s voice line is clear and elastic, and the vocal knot is not particularly front, and there is no common sense of "sticking to the face". The low frequency shows that the dive is fast, the rebound is appropriate, and the amount is medium, so you won’t feel the boom. The resolution of high frequency on iPhone7 is still good, and there is no "harsh" feeling, while the extension performance is excellent.

1MORE’s three-cell ring iron earphone Lightning digital versionWith iPhone7

Editor’s comment:

　　　　I didn’t feel any trouble with this headset, because the iPhone7 came with a patch cord, so the 3.5mm headset can be used as usual. At the same time, the AirPods headset has been released recently, which can be said to be seamless, and there is no need to consider the fetters of wires at all. However, it is a little difficult to grab this headset, and it will take nearly 6 months to deliver it. It is better to replace the headset with the Lightning digital version interface, such as the 3-cell iron headset of 1MORE, which was simply evaluated above.

Traditional manufacturers play HiFi, and the sound is not bad. Cool 1S

　　　　This model not only has excellent performance, but also has remarkable accessories, especially headphones. For example, it is equipped with AKG custom headphones (the author studied it, and this headset is AKG high-end HiFi headphones).

Better resolution and clearer sound quality (quoted from Cool official website)

　　　　This audition experience can be said to be very good, not only the interface is very friendly, but also the operation can be very simple. At the same time, it also integrates a very good concert ticket purchasing function, so that you can enjoy the charm of music at the same time. It can be said that Cool 1S has truly achieved HiFi-level sound quality in terms of sound, not only with the built-in Harman Clari-FI sound source restoration algorithm, but also with the LiveStage virtual surround sound effect algorithm, so that the sound quality can be perfectly restored from the details to the sound field.

Editor’s comment:

　　　　The configuration of this mobile phone is also good: S1 adopts Qualcomm Snapdragon 821, screen, IMX298 sensor, equipped with rear camera and 0.1 second speed PDAF phase focusing technology; The 8-megapixel front camera can achieve a super-large pixel size of 1.4 μ m. Equipped with a large battery capacity of 4070mAh and AKG custom headphones, it can be said that it is an all-round mobile phone for HiFi to listen to music and play games.

　The first ES9038 high-quality chip.　

　　　　Supporting DSD in hardware decoding is simply a bunker, and vivo is the first audio chip of ES9038, which I am very concerned about. Furthermore, supporting hardware decoding will further improve the sound quality, and at the same time, three OPA1622 can provide a good thrust, so it is no problem to carry big ears.

　　　　Friends who used to watch the author’s evaluation before will be very curious. Why not evaluate the mobile phone sound? No, I’m trying vivo Xpay6 these days. The sound quality of this mobile phone still needs to be explained, because this mobile phone uses ES9038 chip, and this author can only find the data of ES9038 PRO:

Unfortunately, ES9038PRO will not appear on mobile phones (quoted from ESS official website).

　　　　ES9038PRO is a DAC chip with the highest index in the industry, with signal-to-noise ratio as high as 140dB and total harmonic distortion plus noise of -122dB. At the same time, it is a 32-Bit, 8-channel DAC. From the parameter point of view, ES9038PRO is enough to kill all opponents in the market, and it also successfully took over from the flagship ES9018S(129dB, -120dB) of the previous generation.

　　　　But the mobile phone is not available.

　　　　So the author went to the official website of vivo to find out and saw the introduction on the official website of vivo:

DSD hardware decoding is the highlight (quoted from vivo official website)

　　　　It can be found that in addition to starting ES9038, there are three operational amplifiers OPA1622. In fact, the most important thing is to support DSD hardware decoding. When you see DSD, someone may ask what format it is. In fact, this evaluation is mainly about lossless sound quality: nothing more than WAV and format, but the DSD format file is actually fundamentally different from WAV and FLAC. I won’t explain here such very profound words as WAV encapsulated in pulse code modulation format, DSD using pulse density modulation (PDM) and so on. But the author also briefly summarized it.

DSD format is still very advantageous.

Advantages:

　　　　1. Compared with WAV and FLAC formats, WAV has a higher sampling rate. Generally, WAV has a sampling rate of 44.1KHZ, while DSD can reach 176KHZ if converted into PCM format because it is a single bit stream.

　　　　2. The noise above the sound will be much cleaner. This has a great relationship with the role of the modem, which directly concentrates the noise on the UHF part.

Summary:　

　　　　These mobile phones really let you see the mainstream music HiFi mobile phones in 2016. Whether you want to listen to songs with a good sound quality mobile phone or an audio enthusiast, these HiFi music mobile phones introduced by the author here are all models that can represent the mobile phone market in 2016. This is equivalent to a review, or please be calm and wait for the author."2016 mainstream music mobile phone inventory test and listening"In this article, the author will use the sound card to install RAMM for testing, and then combine the corresponding sense of hearing.

Original Time School Research Institute Time School is included in the topic # 56 anti-aging substances.

editorial comment/note

Curcumin, which is a’ youth medicine’ and a delicious food, has always had its own place in the anti-aging circle, but it is safe and has no toxic and side effects, but it has not yet been among the top anti-aging products. If you want to listen carefully to the reasons, let’s start with the story of curcumin. ……

Last time, we talked about that a large number of cellular, molecular and clinical studies have proved that curcumin has multiple effects such as anti-inflammatory, anti-oxidation, anti-cancer and anti-microbial (click Review:), but why hasn’t curcumin been licensed and can’t it play a higher role in disease treatment?

Look at people by their character, and look at chemicals by their physical and chemical properties. First of all, we should grasp two characteristics of curcumin: low solubility and unstable chemical properties. Remember these two clues, and the following stories are based on them ~

Low solubility

There is a large hydrophobic region in the molecular structure of curcumin, which determines its basic characteristics of low water solubility. However, there are three hydroxyl groups in its molecular structure, so when the alkalinity is high enough, the charged hydrogen ions will be dissociated, and the curcumin molecule will also be negatively charged, and the water solubility will increase [1]. To put it simply, it is insoluble in water, and the more alkaline it is, the more soluble it is.

instability

Curcumin is a difficult master, and it will change when the environment is a little unsatisfactory. As mentioned above, the greater the alkalinity of the solution, the more curcumin is dissolved, which provides great convenience for the hydrolysis reaction; In addition, curcumin is also easy to occur in the presence of light; What’s more, curcumin may spontaneously oxidize when there is no stimulus! Although so many degradation products have more or less anti-inflammatory and anti-cancer effects, the "periphery" is not as powerful as the "main body" [2].

Then we need to know what curcumin has experienced from eating to discharging, as shown in the following figure [3]:

There are three paths for curcumin to enter digestive tract.

1. In the original form, excreted by feces, jump to the ending 1.

2. After being metabolized by enzymes in digestive tract, it is excreted by feces in the form of metabolites, and jumps to the end 1.

3. Escaped from the clutches of digestive tract enzymes, successfully approached intestinal epithelial cells and entered path B.

There are two ways for curcumin to get close to intestinal epithelial cells.

1. Thrown back to the intestine by the ruthless porters of intestinal epithelial cells, and returned to the path A.

2. Being sent into the blood circulation by the friendly porters of intestinal epithelial cells and entering the path C.

There are two ways for curcumin to reach the liver after it enters the blood circulation.

1. It is metabolized by enzymes in the liver and enters the systemic blood circulation in the form of metabolites, and enters the path D.

2. Escaped from the clutches of liver enzymes, and entered the systemic blood circulation in its original form, and also entered the path D.

After curcumin or its metabolites enter the systemic blood circulation, there are two paths.

1. Enter the kidney with blood, then enter the urine, and pass out of the body with urine, and jump to the end 2.

2. With the distribution of blood to various organs and tissues of the whole body (such as brain, lung, heart, muscle, etc.), it plays an anti-inflammatory, anti-oxidation and anti-cancer role, and jumps to the ending 3.

Obviously, we have high hopes for the ending 3, but how many "difficulties and dangers" does curcumin have to go through to get on this right path? And don’t forget curcumin’s bad temper (low solubility and low stability), so it is even more difficult for it to "survive" success. Therefore, scientists have developed a lot of equipment for curcumin in order to help it succeed.

The role played by these equipments can be summarized as two aspects:

On the one hand, it improves its basic performance (increasing solubility and stability), and on the other hand, it specifically resists "enemy" forces (such as antagonistic cell efflux transporters). The following table is a summary of various methods and principles to improve the absorption and utilization rate of curcumin [3]:

Method type

give an example

principle

Control environmental conditions

Use organic solvents

Increase solubility

Adjust pH

Increase stability

Combined adjuvant

Piperine, catechin, etc.

Inhibition of efflux transporter

Antioxidants such as ascorbic acid and gallic acid.

Increase stability and reduce oxidative degradation.

Packaging technology/carrier technology

Micellar, microemulsion, hydrophobic biopolymer particles, liposomes, etc.

Increase dispersibility in water; Isolate water phase to increase stability; Increase the affinity with tissues and cells

In the research of pushing curcumin into clinical application, the obstacles encountered are not only the above physical and chemical characteristics and biological characteristics of curcumin, but also the research itself:

First of all, curcumin used in various studies is actually different. Most crude extracts made from turmeric and even some refined "curcumin" raw materials contain three main compounds: curcumin, demethoxycurcumin and bis-demethoxycurcumin, and a few secondary metabolites.

The ratio of curcumin compounds in various "curcumin preparations" is different, and the types of curcumin compounds used in experimental research are also different (pure curcumin is often used in in vitro research and more is artificially synthesized, while the mixture of curcumin compounds is often used in in in vivo research and clinical trials), but curcumin is often used as the active ingredient to evaluate the efficacy. In addition, the dosage form and dosage of curcumin used in each experiment are also different. Therefore, it is difficult to compare the effects of curcumin between different studies, and it is difficult to get a consistent conclusion [5].

///

On the other hand, curcumin is a pan-screening interfering compound, which makes it difficult for researchers to judge whether curcumin plays a role in a certain target.

The so-called pan-screening interfering compounds mean that they do not act on the target target but present a sharply confusing false positive result.

Real drugs can precisely act on specific protein binding sites, thus inhibiting or activating the function of protein. The "false positive compounds" are disguised as drug combinations, and smoke bombs are released in various screening studies. Moreover, curcumin does have a wide range of biological activities, just like an all-round sports fan who can win an excellent participation award in various competitions. Therefore, it is not a simple matter to judge whether curcumin has played a valuable role in some way and can be detected correctly [5].

With this explanation, it seems that curcumin is still far from being used as medicine, but there is no need to worry. The above problems are what scientists are trying to solve.

Last time, I made it clear that clinical studies show that taking curcumin up to 12g per day has no side effects, and the FDA also lists curcumin as a recognized safe food additive. We often eat curry, which is healthy and delicious. Isn’t it delicious? As a dietary supplement, curcumin products can also be eaten.

The following summarizes some kinds of turmeric derivatives in life and their uses [6]:

Once again, the content of this article is not used to persuade people to quit. We are just adhering to the consistent style, putting facts and being reasonable! Curry tastes good, so can curcumin ~

Cctv news There is a warm-hearted landlady in Yanjiao, Hebei Province. Not only did she not raise her rent for five years, but she also helped the tenants who came to work in Beijing to grab tickets during her stay in Spring Festival travel rush. She was called "a good landlord in China" by people around her.

In the rented house in Yanjiao Primary School, the tenants are all migrant workers from Henan, Anhui or Sichuan. They go to Beijing to work during the day and return to Yanjiao to rest at night, which is very hard. Seeing that the Spring Festival is coming, because they don’t know how to buy tickets online, a small ticket makes them worry.

After hearing these things, the enthusiastic landlord and aunt decided to help them buy train tickets for a reunion year. The landlady is over 60 years old. Don’t look at her age. She hasn’t left behind any new technology and gadgets. She never leaves her smartphone, video chats with her son and grandson, makes friends, and grabs red envelopes. It is said that some time ago, double 11 also killed many trophies with her mobile phone.

In order to help migrant workers’ tenants to grab train tickets home, my aunt watched the news all day and searched online for ticket buying strategies. She not only wrote a ticket grabbing tutorial for tenants, but also personally helped to grab tickets. The raiders for grabbing tickets compiled by her detailed the date of grabbing tickets, cross-site ticket purchase, leak-detection skills, precautions and so on.

On the wall of the small courtyard, there is a four-page ticket-grabbing tutorial handwritten by the landlord aunt. At the end of the raiders, there are many things to pay attention to when buying tickets and traveling. It can be said that everything is written clearly. Aunt also provides free WiFi, which can’t be more intimate.

For tenants who don’t have online banking and smart phones, the landlord and aunt also help to grab tickets. Less than 8 o’clock in the morning, the aunt took out a notebook with the tenant’s ID number and ticket purchase information, and quickly used her mobile phone to help migrant workers grab tickets. The "good name" of the landlord’s aunt has spread more and more widely nearby. In addition to her own tenants, there are many migrant workers nearby who come to the door for help. It is said that from the beginning of this year to now, the landlady has helped more than 30 migrant workers buy train tickets to go home.

It is understood that the landlady’s wife died early, and her children and grandchildren immigrated abroad a few years ago. Aunt’s old life is very simple, walking the dog, brushing WeChat and visiting the park. For the matter of helping to grab tickets, the aunt is also very real: "It is not easy for migrant workers to work hard outside. Every day, they earn money and save money in the dark. The children in their old home are looking forward to their going home for the New Year. Nothing is more important than a family reunion! I also try my best to help if I can. "

It is not easy for migrant workers to drift out to work. Fortunately, they can meet such a good landlord and aunt. Although it is only a small train ticket, it is actually a reunion of families and the warmth from this society. Netizens have commented: Aunt is really a clean stream in the landlord world, and she is a good landlord in China! Let’s say thank you to this enthusiastic landlord here!

1905 movie network news　　On June 11th, the first press conference was held in Beijing, which was the return of writers and directors Yan Fei and Peng Damo after three years. On the same day, they also led the full cast of Shen Teng, Vivian Sung, Zhang Yiming, Chang Yuan and Wei Xiang.

Shen Teng

As the name suggests, Shen Teng, the star of the film, unexpectedly inherited 1 billion inheritance in "The Richest Man in Xihong City" and became a rich man, so his appearance on that day was also quite imposing — — Not only wearing mink and sunglasses, but also four bodyguards. From the previously exposed trailer, we can see that Wang Duoyu, played by Shen Teng, is quite profligate in "The Richest Man in Xihong City": stocks have to buy the sunset industry that has fallen the most, houses have to live in giant castles, and eating must be lobster … However, in actual shooting, the situation is quite the opposite.

Vivian Sung

According to Shen Teng, the sports car houses in the movies are rented, so needless to say, even those "delicious foods" are fake, and I didn’t eat them at all. However, these testimonies were "refuted" by two directors: abalone and lobster are both real, but because NG shot too many pieces, abalone was hard to cook, so it was mistaken for props. Not only that, the two "thrifty" directors also assured the investors: "All the props were not wasted. We used a fish for three months and finally ate it."

Before Shen Teng became the richest man, he was actually the goalkeeper of the third-class team Daxiang in the fourth-tier city of Xihong. At first, Yan Fei and Peng Damo also hoped that Shen Teng could lose weight, but Shen Teng had to stop fitness training because of hydrops on the femoral head during exercise. Although the scene about this process is still joking, Shen Teng has been struggling with "illness" in the process of filming "The Richest Man in Xihong City" and "Harmony".

Shen Teng’s on-site suit buttons burst open and provoked hilarious laughter

However, as a comedy, The Richest Man in Xihong City admitted that it had no intention of "selling badly" in the publicity process. Shen Teng said that many films will say that their productions are sincere. "We are not only sincere, but also really funny." Not only that, he also lamented the bad movies in the comedy movie circle: "I can’t stand many people who have no sense of humor to manipulate comedy."

Director Yan Fei and Peng Damo.

On July 27th, "The Richest Man in Xihong City" will land in the mainland cinema. Three years ago, "goodbye mr. loser" created a miracle of the dark horse’s counterattack, and the creators also hope that the audience can go into the cinema to support this new film this time. Director Peng Damo also said that the performances of these actors in "The Richest Man in Xihong City" are also the best among all comedies.

Recently, Bo Huang, a famous actor and vice chairman of the Chinese Film Association, made an in-depth discussion on the present situation and future development of the film industry in China when interviewed by Xinhua News Agency. He said that in the face of drastic changes in the industry, embracing innovation and change is the key to grasping new opportunities.

Bo Huang pointed out that in recent years, China films have made unprecedented progress, but the rapid development of the industry is also accompanied by no small challenges. He emphasized that only in a dynamic environment can creators find new inspiration and opportunities. He is convinced that only by sticking to the roots of the people and understanding the needs of ordinary audiences can we inject more vitality into film creation.

Through many years of acting experience, Bo Huang understands that the audience’s love stems from the real description of life. He started from a small role and has gone through numerous tempering. Now he has become a movie star familiar to the national audience. He mentioned that paying too much attention to box office data may affect the essence of creation, and some innovative works are still worth exploring and trying even if the market response is dull. The "HB+U" new director assistance program initiated by him is a typical case, which aims to support young film creators and promote the inheritance and development of film art.

When talking about his creative changes in recent years, Bo Huang said that he stepped out of the high-intensity work state and tried many different roles and art forms. For example, in 2023, he participated in many films with different styles, including "Enthusiasm" and "Gods", which reflected his diversity and exploration spirit in role selection. Bo Huang believes that an actor’s performance experience and creative inspiration must come from his careful observation and experience of life. He has realized that stopping, slowing down and communicating with people outside the film circle can make his creation deeper.

Looking into the future, Bo Huang thinks that the film industry in China is undergoing a great change. For example, with the emergence of new technologies and platforms, the audience’s viewing habits are also changing. He mentioned that his predecessors told him that the sense of life in movies originated from the gear sound of that projector, but with the development of science and technology, we must accept this reality and use new technology to bring more possibilities to movies. He admits that the rise of artificial intelligence may change some links in the film and television industry, which is undoubtedly a challenge, but it is also an opportunity.

Bo Huang said that at present, China has become the second largest film market in the world, which provides a broader stage for creators. While mastering advanced technology and improving the shooting level, we should not only pay attention to the commercial success of the works, but also pay attention to their artistic quality and social value. He firmly believes that always putting people at the center of creation can provide inexhaustible motive force for the progress of movies. Bo Huang’s point of view not only points out the direction for film creation, but also brings profound thinking to industry practitioners.

China’s films are moving towards a more brilliant future. Only those creators who can adapt to changes and dare to try can stand out in this surging market competition. Bo Huang’s ideas and practice undoubtedly provide us with important enlightenment: drawing inspiration from life, taking root in the people and embracing change are the fundamental driving forces for the vigorous development of future films. All this is in the ever-changing era, looking forward to the next new chapter of the film.

Editor in charge:

　　After visiting the Light of the Internet Expo, do you still remember the various "black technologies" at the exhibition? Tmall unmanned supermarket, sogou Wangzai robot, Baidu robot … … The high-tech of the Internet has been integrated into all aspects of life, which makes people feel deeply and still leaves much to be desired.

　　However, the annual Internet Light Expo is always only a few days. When many people have no time to feel the "black technology" at the forefront of the Internet, it has already ended and they can only look forward to the next Expo. However, the reporter found a brand-new "Expo" that is open to the public all year round during his recent visit — — Wuzhen Summit Internet Application Experience Center. The brand-new experience center is located in Wuzhen Street in the west of Wuzhen Bridge. On the day of the reporter’s visit, the experience center has entered the final stage of decoration. According to Zhu Zhaokui, assistant general manager of Zhejiang Wuzhen Street Technology Co., Ltd., the experience center will be officially opened soon.

　　"You’ll know what kind of shoes are suitable for you at one stop."

　　Red Dragonfly "Smart Store" officially entered the Experience Center.

　　Entering the brand-new experience center, the decoration has entered the final finishing stage, and some "black technology" booths have been put in place in advance, including the Red Dragonfly "Smart Store" on the south side of the experience center.

　　"Hello, do you need to experience our latest intelligent service of Red Dragonfly? Just one stop up and you will know which shoes are right for you. " Just before walking to the booth, Huang Yali, the person in charge of the personalized smart store of Hung Hom, warmly greeted Xiaobian. Take off your shoes, socks, stand on the foot scanner, and the foot scanner scans and measures the foot shape. The whole process takes less than 5 minutes. On the electronic display screen right in front of the foot scanner, a small exclusive "Red Dragonfly Foot Scanning Report" is issued, which covers all the foot shape information of the reporter, such as foot width, toe length and foot shape.

　　"With this foot information and uploaded to Alibaba Cloud, our back-end system will have a complete ‘ Foot file ’ , through this file, our ‘ Intelligent system ’ We will recommend all kinds of shoes that best suit his foot type for customers to choose. " Huang Yali told Xiao Bian that because everyone’s shoe type is different, we can better understand the customer’s foot type through the way of "internet plus Store", and naturally we can provide them with exclusive shoe recommendation and service. Today, Red Dragonfly has opened more than 10 "smart stores" in China.

　　Experience center "black technology" contended.

　　On the right side of Red Dragonfly’s "Smart Store", a self-service vending machine named "Youbao" caught the attention of Xiaobian. The seemingly ordinary self-service vending machine actually has the latest new technology of the Internet — — Pay by brushing your face.

　　After selecting the beverage that you want to buy, the reporter clicked the option of "brush face to pay". After Xiaobian brushed his face for the first time, the prompt of "Enter the bound Alipay mobile phone number" popped up in the background of the system. After entering the mobile phone number, the beverage was purchased successfully. After several purchases, the prompt "Enter the bound Alipay mobile phone number" will no longer be displayed, and the purchase can be successful by directly sweeping the face.

　　Bring VR glasses and stay above Wuzhen, and the whole picture of the town comes into the eye of Xiaobian with the flight trajectory … … In the "Leyou Wuzhen" VR flight somatosensory project of Zhejiang Zhongnan Cartoon Co., Ltd. on the east side of the experience center, the reporter really experienced the fun of flying through the air and overlooking Wuzhen. Of course, in addition to the aerial view, the project also has a 360-degree panoramic mode. When switching to this scene, Xiaobian "walked into" the corners of Wuzhen with the mode of the first perspective. "In this VR experience, we have set up two modes, dynamic and static, for the public to experience. The purpose is to show the customs and humanities of Wuzhen in all directions through VR." Mr. Jin, the equipment manager of Zhongnan Cartoon Co., Ltd. said that this booth will continue to be open until next year’s world internet conference Wuzhen Summit. At that time, if there are any newly developed products, the company still hopes to return to the Experience Center to show them to everyone.

　　It is reported that the Experience Center is jointly built by the Information Department of the General Assembly, the Light of the Internet Expo and CLP Haikang, which brings together the new technologies in Internet application facilities of 20 enterprises including China Electric Branch, China Telecom, CLP Haikang, sogou, Red Dragonfly and Good News Bird. Different from other exhibition halls, Wuzhen Summit Internet Application Experience Center will be open all year round, and interested friends can visit the latest "black technology" on the Internet at any time. At the same time, Wuzhen Street Company is also an Internet of Things incubator in Tongxiang City, and will continue to promote all kinds of high-quality Internet application projects in Tongxiang. "During the upcoming 5th world internet conference Wuzhen Summit, a number of projects cooperated by CLP Haikang Group and Wuzhen Street Internet of Things Business Incubator have contributed to the intelligentization of this conference, including high-density channel WiFi2.0, Hikvision intelligent transparent large screen and so on." Zhu Zhaokui said, "Most enterprises that provide intelligent promotion support are excellent enterprises that have been incubated and cooperated with Wuzhen Street, an innovation and entrepreneurship platform. We hope that by creating benign ecological circle resources, Wuzhen Street enterprises can further achieve a win-win situation and develop hand in hand."

Xinhua News Agency, Zhengzhou, July 29th Title: This enterprise makes China’s shield machine go global.

Xinhua News Agency reporters Ma Yizhen and Han Jianuo

At the entrance of the shield assembly workshop of China Railway Equipment, a blue and white shield cutter head with a diameter of nearly three stories is being hoisted on a heavy transport truck, and it will be put into the Tel Aviv subway tunnel project in Israel soon. This is also the eighth shield machine exported by China Railway Equipment to Israel in recent years. In addition to Israel, the company’s shield equipment exported to Austria, Italy, Portugal, Qatar and other countries has also been rolled off the assembly line and installed …

How did this company make China people’s own shield machine? And how to make China’s shield machine go to the world by virtue of its strong strength? A few days ago, the reporter walked into Zhengzhou headquarters of China Railway Engineering Equipment Group Co., Ltd. and felt the invincible power of big countries.

Build China’s own shield machine.

According to the relevant person in charge of China Railway Equipment, full-face tunnel boring machines are divided into hard rock boring machines, earth pressure balance shield machines and mud-water balance shield machines according to different applied geological conditions. In China, the latter two types are commonly referred to as "shield machines". This kind of equipment is called "the king of construction machinery", which integrates mechanical, electrical, hydraulic, sensing, information, mechanics, guidance research and other technologies. A shield machine is several stories high, weighs thousands of tons, and has tens of thousands of parts. The control system alone has more than 2,000 control points.

Wang Dujuan, chief expert and deputy general manager of China Railway Engineering Equipment Group, told the reporter that in the past, underground tunnels were the difficulties of many major projects. Traditional excavation and excavation relied on methods such as pneumatic drilling, blasting and stone slag planing, which had low safety and efficiency.

In order to speed up the infrastructure construction, in the 1990s, China imported two hard rock boring machines from abroad at a cost of 700 million yuan, which were used for the construction of Qinling Tunnel on Xikang Railway. However, these imported machines are not only expensive, but also cost more for follow-up services.

Wang Dujuan and his colleagues sprouted a dream from their hearts: China people must build their own shield machines! Later, she and her colleagues made repeated investigations and attempts, and started over and over again … In April 2008, we finally successfully developed the first composite EPB shield machine with independent intellectual property rights in China. Subsequently, the prototype was applied to the Tianjin subway project, which not only made the excavation speed fast, but also controlled the surface settlement within 3 mm. After the success of the first battle, this meritorious shield machine was officially named "China Railway No.1".

Polishing high-end equipment and manufacturing "business cards"

After the breakthrough of domestic shield machine from scratch, it is inseparable from the continuous innovation of technology to continue to achieve from scratch to strength and rank among the top in the world.

In the aspect of intelligent product innovation, the traditional tunnel boring machine (TBM) construction operation is to dig horizontally, but when digging wells, for example, the TBM needs to dig vertically. In order to meet the demand of vertical excavation, China Railway Equipment has carried out scientific research for another ten years.

"Why don’t we apply the concept of full-face tunnel boring machine to shaft boring machine, develop new products and open up new categories?" In December 2012, Li Jianbin, then Party Secretary and Chairman of China Railway Equipment, said at an internal technical seminar. After analysis and discussion, the participants immediately began to prepare for the research and development of full-face hard rock shaft boring machine.

In order to design a shaft boring machine with few people, no one, mechanization and intelligent construction, R&D personnel personally built a shaft with a depth of 690 meters, and tackled the slag tapping technology, propulsion technology and remote control technology one by one.

Finally, in 2021, the full-face hard rock shaft boring machine developed and manufactured by China Railway Equipment for 10 years was successfully used, which overcame the world problem of shaft boring for 1,000 meters and realized the concept of "drilling without lowering the well, intelligent boring" for the first time.

At present, China Railway Equipment is actively deploying intelligent shield machines and future boring machines, facing the forefront of industrial technology development, and carrying out reserve research on new rock-breaking technologies such as laser and water jet, tool-changing robots and unattended intelligent tunneling technologies. It has successively won the first and second prizes of national scientific and technological progress, a single champion demonstration enterprise in manufacturing industry, a gold medal in China’s good design, a silver medal and a gold medal in China’s patent. In 2020, China Railway Equipment was successfully selected as the first batch of "Science and Technology Reform Demonstration Enterprises".

"selling the world" opens a new journey

Wang Jinsong, head of the equipment quality management department of China Railway, told the reporter that the underground construction environment of roadheader is poor, the safety risk is high, and the equipment requirements are high. How to control the product quality is the primary problem faced by production enterprises. China Railway Equipment pays attention to detail control, focuses on product quality upgrading, implements lean production, implements quality one-vote rejection system, process real-name registration system and three-level inspection system, and fully guarantees product quality.

In recent years, China Railway Equipment has been climbing the technical peak of roadheader, and its products and services have been widely recognized by the international market. In 2021, the hard rock roadheader "Caucasus" made in China was officially excavated in the Georgian highway tunnel. The equipment has a diameter of 15.08 meters and a total weight of 3,900 tons. It is completely designed by China and China standards, and is independently manufactured by the Chinese side. It has an efficient tunneling capability under the conditions of long distance and large buried depth. This equipment has set a new record for the excavation diameter of hard rock roadheader in the world, and it is also a powerful witness for China Railway Equipment to serve the global underground engineering construction.

The picture shows that on December 4, 2019, two large-diameter EPB shield machines applied to Paris Metro Line 16 were officially launched at Zhengzhou Base of China Railway Engineering Equipment Group. (Photo courtesy of China Railway Equipment)

In recent years, the tunnel boring machine produced by China Railway Equipment is becoming a new domestic product of "Belt and Road". In 2015, China Railway Equipment won the bid for multiple shield machines in Tel Aviv subway in Israel at one time; In 2018, it won the bid for the Copenhagen project in Italy and Denmark to enter Europe; Successfully exported to France in 2019 for the Paris subway project; In 2020, the slurry shield machine exported to Poland …

In the first half of this year, China Railway Equipment actively overcame the impact of the epidemic, seized opportunities and overcome difficulties, and went all out to promote the efficient implementation of various economic indicators. The amount of newly signed contracts increased by 58% year-on-year, achieving a contrarian rise.
