Recently, East China, North China, Northeast China and other places have continuously suffered from heavy rainfall, causing floods and geological disasters, causing heavy casualties and property losses in many places. Under the strong leadership of the CPC Central Committee with the Supreme Leader as the core, the relevant localities and departments responded and dealt with it at the first time, comprehensively compacted their political responsibilities, and implemented various flood control measures with practical actions. At present, flood control, emergency rescue and disaster relief work are carried out in an orderly manner to fully protect people’s lives and property.

On July 28th, the National Flood Control and Drought Relief Headquarters launched a three-level emergency response to Beijing, Tianjin and Hebei, and three working groups sent by the National Flood Control Office have been sent to the three provinces and cities to help guide the flood control and disaster relief work. The National Disaster Prevention, Mitigation and Relief Committee launched the national four-level emergency response to disaster relief. The National Development and Reform Commission urgently arranged for the central budget to invest 50 million yuan to support Hebei’s emergency recovery after the rainstorm and flood disaster.

On the 28th, the Beijing Flood Control Headquarters launched the city’s first-level emergency response to flood control. The school stopped all offline teaching activities and field teaching activities, closed all scenic spots, parks and forest farms, and evacuated threatened tourists. Tianjin Planning and Natural Resources Bureau and Tianjin Meteorological Bureau jointly issued meteorological risk warning of geological disasters. Xigou Village, Mayingzi Manchu Township, Luanping County, Chengde City, Hebei Province, caused a landslide due to heavy rainfall, and the local authorities quickly organized forces to carry out rescue. Relevant rescuers have arrived at the scene to search and rescue the missing persons.

　　[PConline evaluation]Now, it has been one month since Intel released the third generation Core i5/i7, and the replacement process of the old and new handover seems smooth. Intel Core i5 3450, as a new younger brother in the i5 series, is used to replace the original Core i5 2300/2320/2400 market. Recently, however, AMD quietly lowered the price of the flagship model processor FX-8150 to 1300 yuan, and the Core i5 3450 was attacked head-on. In the face of strong enemies, can Core i5 3450 cope?

● Market positioning of ●Intel Core i5 3450

　　Intel Core i5 3450 belongs to the third-generation Core i5 series. According to Intel’s plan, it is used to replace the second-generation Core i5 2300/2320/2400. The price is in the early thousand yuan, and it mainly focuses on the thousand-yuan market.

Core i5 3450 focuses on the thousand-yuan market.

　　The main difference between Intel Core i5 3450 and Core i5 3570K is that the former can’t overclock, except for the difference in frequency. However, with P67/Z68/Z75/Z77, four additional octaves can still be obtained.

● competitors of ●Intel Core i5 3450?

　　Before Ivy Bridge was released, Intel Core i5 had no competitors at the price of 1,000 yuan. But recently, AMD’s eight nuclear bulldozer has gone through several price dives and reached the price of 1,300 yuan, directly competing with Intel Core i5 3450. Who wins and who loses? We will reveal it in this PK.

AMD FX-8150 directly impacts Intel Core i5 3450.

● Analysis of ●Core i5 3450 specification

　　Core i5 3450 adopts 22nm process and is designed based on Ivy Bridge architecture. It is native with four cores and four threads, and the default frequency is 3.1GHz, which can be turbo-charged to 3.5Ghz, with 6MB of three-level cache. The core graphics card is integrated with HD2500, the default frequency is 650-1150MHz, 6MB L3 cache is shared with CPU, and the thermal power consumption of TDP is designed to be 77W.

Intel Core i5 3450　　picture　　series　　evaluating　　forum　　quote　　Net purchase price

　　For more detailed specifications, we can refer to the following table, and compare Core i5 2300, Core i5 3450, Core i5 2500K and Core i5 3570K together:

　　It can be seen that the frequency of Core i5 3450 and Core i5 2300 is 0.3GHz higher than that of Core i5 2300, and the core frequency amplitude is also a complete four octaves (Corei5 2300 has only three octaves). In contrast, the specification of Core i5 3450 is closer to that of Core i5 2500K. However, because it doesn’t support hyper-threading technology, the whole series of Core i5 is four cores and four threads. Facing the impact of the competitor FX-8150 with four modules and eight threads, does i5-3450 have a chance of winning? Next, let’s start testing.

2. Introduction of evaluation platform and method description

　　Some time ago, we have tested the performance of the core graphics card of Core i5 3450, so this paper only tests the CPU part, and will not repeat it. If you want to know this information, you can clickhereRefer to the previous evaluation articles.

　　The object of this evaluation is Core i5 3450, which is used to replace Core i5 2300/Core i5 2400 series; We add Core i5 2300, Core i5 2500K, Core i5 3570K and FX-8150 for comparison. The evaluation items include theoretical multithreading performance test, common software test, professional application test, game test, power consumption test and overclocking test.

　　In the mid-to high-end market, there is also E3-1230 V2, which has been popular recently, but strictly speaking, it does not belong to the desktop platform products under normal channels, so we will not compare it here. For the performance of E3-1230 V2, you can click.hereLearn more.

The 8-thread FX-8150 makes up for the deficiency of the core architecture to some extent, and the test results are similar to those of the previous theoretical multi-thread performance evaluation.

3.4. Physical operation: 3DMark Vantage and 3DMark 11 evaluation.

　　This part of the test mainly examines the physical operation and artificial intelligence operation ability of CPU in the game. We choose the authoritative 3D testing software 3DMark Vantage and 3DMark 11, which are the testing software of DX10 and DX11 respectively.

● DX10 test software 3DMark Vantage:

3.5、Game performance evaluation

　　In the game testing part, we selected StarCraft II: Wings of Freedom, Grand Theft Auto 4: Chapter of Freedom City and resident evil 5 for testing. Although they are not the latest games, they put high demands on the CPU, and the test results can better reflect the game performance gap between the CPUs.

● DX9 game StarCraft II:

Resident evil 5 test scores.

　　Test summary:Compared with two generations of Core i5 2300, Core i5 3450 in the game test still keeps ahead. It can be seen that Ivy Bridge has indeed made progress compared with Sandy Bridge, but in the face of scores of hundreds of frames, the gap of 10 frames is actually not obvious. FX-8150′ s test in these two rounds is more tragic, because at this stage, the game has limited optimization of multi-core, and the test is actually the performance of single core.

3.6 Platform power consumption test

　　Because the individual power consumption of CPU can’t be accurately measured in general environment, we test the power consumption of the whole platform in the power consumption test part. By investigating the power consumption gap of each platform, the power consumption gap of each CPU is indirectly reflected. We chose the famous baking machine software Prime 95, and adopted the Large mode to make the CPU and memory work at full load, while the graphics card was not at full load, and then recorded the readings on the power consumption meter.

Test of baking machine with Prime 95

Comparative evaluation of platform power consumption — — Standby (The graphics card is in standby state.)

Comparative evaluation of platform power consumption — — Fully loaded (The graphics card is in standby state.)

　　Because of the Turbo function, the power consumption of the four Core i5 products in standby state is basically the same, and the difference between them is mainly reflected in the full load state. It can be seen that the full-load power consumption of Core i5 3450 is about 10 watts lower than that of Core i5 2300. As for competitors, the power consumption brought by FX-8150 with four modules and eight cores is still very large.

3.7. Free lunch! Overclocking Test of Extra Quadruple Frequency of Core i5 3450

　　As mentioned earlier, Core i5/i7 (non-K series) with P67, Z68, Z75 and Z77 motherboards (other models are not available) can be overclocked in a small range, with an amplitude of 4 octaves. So weDirectly increase the frequency of Core i5 3450 by four times in the BIOS, set it successfully and enter the system directly. At this time, the frequency is 3.5-3.9GHz (single core turbo frequency is 3.9GHz, quad core turbo frequency is 3.7GHz):

BIOS setting method

　　The above is the motherboard used in this test — — Screenshot of BIOS settings of ASUS Saber tooth Z77, the setting path is "Advanced Processor Settings CPU Power Management", in which a default value of CPU ratio is 35 (the highest turbo frequency of i5 3450), and we set it to 39, which successfully booted up and entered the system. Let’s take a look at how much performance improvement is brought by these four extra frequency doubling.

　
3DMark Vantage test: improved by 14%

3DMark 11 test: increased by 11%

Fritz Chess test: increased by 12%

WPrime test: increased by 11%

　　Summary:After four times of frequency doubling, the average performance of Core i5 3450 is improved by 12%, which is higher than Core i5 3570K at the default frequency, and the system runs very stably. We believe that this CPU still has a lot of room for overclocking. Later, we tried to increase the frequency by five times and set the CPU ratio to 40. As a result, it will be reset after each setting. It seems that Intel’s restrictions on overclocking are still very strict, so we can only choose the "K" series model if we want to overclock.

4. Summary of PConline Evaluation Room

　　Some time ago, we have tested the performance of the core graphics card of Core i5 3450, so this paper only tests the CPU part, and will not repeat it. If you want to know this information, you can clickhereRefer to the previous evaluation articles.

CPU performance ranking, based on the CPU score of 3DMark Vantage
(For reference only, it does not represent the comprehensive performance of CPU)

●CPU performance replaces Core i5 2300 without pressure, which is similar to FX-8150 and i5 2500K at the default frequency.

　　We convert the scores of each sub-item in the previous CPU performance test into percentages based on i5 2300, and then take the average value to get the following figure:

CPU performance comparison

　　The performance of Intel Core i5 3450 is 14% higher than that of Core i5 2300. Apart from the architectural advantages, the increase of core frequency is also one of the reasons for this difference, because Core i5 3450 was originally planned to replace two series of Core i5 2300/2400. Even so, the Core i5 3450 will not impact the products of the previous level, and its performance is basically the same as that of the Core i5 2500K at the default frequency. Look at the competitor FX-8150 again, and the comprehensive performance gap between them is almost negligible.

● Power consumption control is still eye-catching

Power consumption comparison

　　The power consumption of Core i5 3450 based on 22nm process is well controlled. Although the turbo frequency is 0.4GHz higher than that of Core i5 2300, the overall power consumption is still great. This aspect has always been the strength of Intel Core series, far ahead of competitors.

● Purchase suggestions

Intel Core i5 3450　　picture　　series　　evaluating　　forum　　quote　　Net purchase price

1. Competitiveness analysis

　　In terms of performance:Core i5 3450Compared with Core i5 2300, it is improved by 14%, and its performance is close to that of i5 2500K and FX-8150 at the default frequency.

　　Power consumption:Core i5 3450 based on the new generation Ivy Bridge architecture has great advantages.

　　In terms of price:Same as FX-8150.

　　The original task of Intel Core i5 3450 is to replace the Core i5 2300/2400 series. Compared with the previous generation, the CPU performance is improved by about 10%, and it will not impact the previous product, so it is not a big problem to successfully take over the market. On the other hand, AMD’s FX-8150 has suddenly cut its price to 1300 yuan recently, which has a great impact on the i5 market.From the test results, the two have their own advantages and disadvantages, but Core i5 is far from the opponent in power consumption control.

2. User groups

　　Mid-to-high-end gamers and users who have certain requirements for performance.

Step 3 buy suggestions

　　If you focus on games and multimedia entertainment, Intel Core i5 3450 is a good choice, because at present, the game is not optimized for multi-core performance, and the four-core four-thread and Ivy Bridge architecture are enough to cope with it. Intel’s advantages in architecture and power control are still obvious; If you want to overclock, you can consider FX-8150. The price reduction of the eight-core bulldozer has been within a reasonable range.

Cctv newsHe works 15 to 18 hours a day. At the busiest time, he needs to be responsible for screening and treatment of three wards, an ICU ward and a fever clinic. Liang Lianchun spent the whole Spring Festival in the hospital. Since the outbreak, he has been fighting in the front line continuously, and his 86-year-old father is looking forward to having a reunion dinner with him, but he has never been able to do so.

Liang Lianchun is the chief doctor in the Department of Infectious Diseases of Beijing You ‘an Hospital, and has been deeply involved in the treatment of infectious diseases for more than 30 years. The fight against the "epidemic" rushed to the forefront of treating diseases and saving lives, and he did not hesitate.

Every day, "stepping on hot wheels", he said that old comrades should take the lead as models.

At the early stage of "anti-epidemic", he judged that the disease was not an ordinary infectious disease and was highly contagious according to the development of the epidemic situation in Wuhan and his own experience in the prevention and treatment of major infectious diseases, so he must adhere to scientific prevention and control and precise treatment.

He formulated standardized diagnosis and treatment measures: three-level diagnosis and treatment system, difficult case discussion, multidisciplinary consultation, individualized treatment plan and the most stringent protective measures. At the same time, he led the You ‘an team into the front line of fighting the COVID-19 epidemic.

The fever clinic is one of the most difficult areas in the whole hospital during the epidemic. After Liang Lianchun took over the fever clinic, he rested at 12 o’clock in the evening and got up at 5 o’clock in the morning. With the increasing number of patients, it takes more than two hours to check the patients once, and several times a day. Wearing protective clothing, Liang Lianchun will feel obviously suffocated and his clothes are soaked just by saying a few more words.

Medicine is benevolence. As a doctor, we should not only solve the patients’ physical pain, but also give them spiritual comfort. Liang Lianchun, while trying to provide the best treatment for COVID-19 patients, also felt the patients’ inner fragility and fear. Therefore, he was always patient and meticulous with patients and tried his best to comfort them.

There have been patients who decided that COVID-19 could not be cured, and they were very excited, which brought great difficulties to medical staff in treatment and nursing. Liang Lianchun communicated with her face to face many times and patiently explained the characteristics of COVID-19. Later, the patient found that the evolution of his condition was exactly the same as that of Liang Lianchun, and he was relieved and actively cooperated with the treatment. After 12 days, she recovered and was discharged from hospital. She volunteered to donate convalescent plasma to treat critically ill patients.

Liang Lianchun believes that veteran comrades with rich experience should play a leading and exemplary role. Although the work is too busy but methodical, colleagues all laugh at him: "Every day is like stepping on hot wheels."　

"The wind and waves are coming," he said. There is no insurmountable difficulty.

Participated in the treatment and prevention of infectious diseases such as SARS, influenza A (H1N1) and plague, Liang Lianchun always said that with the coming of big waves, he can face every epidemic more calmly. Young medical staff were worried about Covid-19 at first, and were afraid of being infected. Experienced Liang Lianchun was the reassurance of the team.

The treatment of critically ill and critically ill COVID-19 patients is the top priority of medical work. A few days ago, a group of 80-and 90-year-old COVID-19 patients with heart diseases were transferred from the outer hospital to Beijing You ‘an Hospital. Their basic diseases were many and severe, and their nutrition was seriously deficient. Hospitals are facing great challenges in terms of professional technology and equipment conditions, which makes medical staff feel great pressure. In this case, Liang Lianchun entered the ICU ward twice a day and learned the first-hand information of each critically ill patient one by one. He met with the members of the expert group for the treatment of critically ill patients every day and made an individualized diagnosis and treatment plan for each critically ill and critically ill patient.

Working day and night, in exchange for more critically ill patients in COVID-19 turned the corner. As of February 26th, Beijing You ‘an Hospital has treated more than 200 confirmed and suspected patients, and more than 70% of the confirmed patients have been cured and discharged.

Liang Lianchun still remembers that in 2009, the influenza A (H1N1) was threatening, and he knew very little about the virus, so he could only learn about it by collecting information from the Internet at any time. From measuring body temperature to making treatment plan, to writing case report … … Liang Lianchun did it himself and stayed in the ward for three days and two nights at the longest.

When Liang Lianchun just graduated, he finally chose radiology because of misunderstanding and fear of infectious diseases. But after five years in radiology, he set a new goal for his medical career — — Go to the infection general department with the highest risk.

Years of experience in dealing with infectious diseases and infectious diseases have given Liang Lianchun an unrepeatable practice experience and medical quality. For the COVID-19 epidemic, he fully understands the worries of young medical staff, but he has no fear at all. In his view, fighting against any virus is just their natural daily work, and it is his most important thing to let all patients go home healthily. (Text/Wang Ruoyi)

Special feature of 1905 film network According to statistics, every three seconds, there will be another patient with Alzheimer’s disease in the world. For a long time, filmmakers have been thinking about how to tell the story of Alzheimer’s disease from different perspectives. On the eve of Mother’s Day, a Japanese film released on May 12th showed this theme again, telling how a son who lacks maternal love can understand his mother’s story by witnessing half of the fireworks. After the film was released, there was a polarization of word of mouth. Some viewers thought it was mysterious, slow-paced, far-fetched to go to the meeting, and the editing was sparse. Another part of the audience thinks that sincerity is delicate and has great stamina.

Lu Jianing, an associate professor at China Communication University, said: "These two views are reasonable. In a few words, it is very personal and tells a case-by-case emotion; The second word to describe the film is dislocation. The child was abandoned by his mother for a year, and his mother went to a new relationship willfully. The child is always fighting for love with a remembered mother lover. Under this mode, he often makes a cold attitude towards his sick mother. The film made the trauma particularly serious. Although Alzheimer’s disease runs through, it has become an opportunity to heal the trauma, which is very different from our understanding of the disease. Its privateness makes the film very delicate, and dislocation will make people feel that it is difficult to identify with many times. "

The film will cause such controversy, which is also related to the cultural differences between China and Japan. "My Last Year with Mom" is full of the aesthetic of mourning for things with Japanese characteristics. When touching external things, I feel deeply touched by the scene and naturally reveal deep and mysterious feelings. The hero has always been very resistant to his mother’s pursuit of half a firework, thinking that this is because she is missing her past lover. At the beginning, it was for this lover that her mother abandoned herself for a year. But it wasn’t until he witnessed it that he found out that what his mother had been thinking about was the half fireworks she saw through the opposite tall building in her hometown. When Alzheimer’s Harmo’s disease erodes the mother’s brain, but it doesn’t take away her love for herself, the most precious memory in her heart is still the happy time when she accompanied her son to grow up.

It is also witnessing the half fireworks with my own eyes, and the memories of living with my mother are pouring in. At that moment, the fleeting beauty in the sky seems eternal. The film uses extremely delicate techniques to let the audience and the hero experience the beauty of this moment. The fireworks are bright and dark in mid-air, and the inanimate objects resonate with people’s strong emotions, which lights up the constant love between mother and son, and also makes the audience understand this affection that blood is thicker than water. As the theme of the film, the creative team did not highlight the suffering of Alzheimer’s disease, but turned it into a key to lead the mother and son to untie the knot.

Nowadays, more and more film creators in various countries pay attention to Alzheimer’s disease, which leads to the birth of countless excellent films. However, different educational and cultural differences in different countries make this theme have completely different interpretations, reflecting different lives of people in different countries. Japanese people tend to film Alzheimer’s disease as a cure film, which weakens the pain caused by the disease to patients and their families, and pays attention to how patients can change their relationship with others through Alzheimer’s disease. For example, in his works, relevant plots have been set, and the characters who were not liked originally changed their personalities after suffering from Alzheimer’s disease, thus repairing the relationship with family and friends. It can be said that such a description will definitely make people feel cured, but it has become an understatement for this disease, lacking profundity and thinking.

Different values present different perspectives, and in European and American films, such as, etc., they are strongly individualistic. In the eyes of western filmmakers, people are lonely individuals. After suffering from Alzheimer’s disease, patients not only lose their memory, but also look at the world in a chaotic way. Even with the meticulous care of their families, it is difficult to enter the inner world of patients. In the context of many western films, move on is emphasized. No matter what happens, people should go on strongly. However, patients with Alzheimer’s disease have lost this strong heart to go on. They are lonely and no longer sure who they are, so their films often make patients full of tragedy. The Father even cried directly to find his mother who died many years ago, which makes people moved.

Influenced by Confucian culture, ethical concepts and realistic aesthetics, China’s creators pay more attention to the blood ties between family idioms when creating related themes, which leads to a more grand view of history and society. Dislocation in the end, let the mother who should have been taken care of heal her daughter with Alzheimer’s disease, no matter how her age changes, maternal love can still make her strong; In the middle school, my son was afraid that his mother with Alzheimer’s disease would get lost, so he connected himself with his mother with a rope, just like an umbilical cord, and took her back to the Mongolian steppe to find her roots. These excellent works reflect the greatest values of China’s family, and also reflect a wider and deeper space on this theme, and express the thoughts of China filmmakers with movies.

Sickness itself is a tragedy, but many people and families presented in the film actually gained another affection in this tragedy and made up for some regret. There is a line saying that life is different from movies, and life is much harder. I hope movies, light and shadow can give you more strength to face this challenge in life together.

　　CCTV News:With the continuous development of social media, "online celebrity" bloggers in fashion, food, fitness and other fields came into being. Some of them share all kinds of useful experiences and suggestions in life, while others use their influence on the internet to mislead fans in order to earn more benefits. Recently, the glamorous image of an American "online celebrity" blogger was debunked, which sounded the alarm for many netizens.

　　Jovana Mendoza, a 29-year-old living in California, USA, declared on the Internet that she became a strict vegetarian in 2013, and gradually became a "online celebrity" by sharing her own recipes. She also opened a personal website and sold various "dietotherapy" courses.

　　However, just last month, Jovana was photographed eating in a restaurant in Bali, and eagle-eyed netizens found fish on the plate in front of her. Angry fans have accused Jovana of pretending to be a vegetarian to cheat money and pay attention. Under pressure, Jovana immediately posted an apology video on the Internet, saying that he started eating fish and eggs two months ago because of health problems.

Since 2017, her body has been suffering from anemia, malnutrition, hormonal imbalance and digestive system disorder. Doctors advised her to change her eating habits and supplement protein, an animal.

　　However, Jovana insists that he still believes that vegetarianism is an active and healthy lifestyle and will continue to promote it in the future. Netizens don’t buy it, thinking that it is very irresponsible for her to hide the facts in order to maintain her image on the Internet and package the extreme diet that causes her health problems into a product that is "free of harm".

　　Washington post pointed out in the report that the massive information on social media is difficult to be regulated and regulated, thus providing a breeding environment for rumors and scams. The glamorous image of "online celebrity" may just be a mask created to attract attention. Whether the products or lifestyles they recommend are trustworthy or not needs careful judgment.

　　According to data released by the National Bureau of Statistics on the 14th, from January to October, the national investment in real estate development was 9,932.5 billion yuan, up 9.7% year-on-year, and the growth rate dropped by 0.2 percentage point from January to September, which was the third consecutive month of decline.

　　Specifically, except for the increase in construction area, other indicators showed a downward trend. From January to October, the housing construction area of real estate development enterprises was 7,844.25 million square meters, a year-on-year increase of 4.3%, and the growth rate was 0.4 percentage points higher than that of January to September. The newly started housing area was 1,687.54 million square meters, an increase of 16.3%, and the growth rate dropped by 0.1 percentage point.

　　"The year-on-year growth rate of land transaction area declined slightly, and the increase in average transaction price narrowed for seven consecutive months." Shen Xin, a researcher at Shanghai Yiju Real Estate Research Institute, said that near the end of the year, considering that the funds of housing enterprises tend to be tight, the pace of land purchase will slow down. At the same time, due to the continuous decline in sales growth, it is expected that the year-on-year growth rate of new construction area will show a slight decline.

　　Judging from the funds in place for real estate, the funds in place for real estate development enterprises in the first 10 months were 1,356.36 billion yuan, a year-on-year increase of 7.7%, and the growth rate dropped by 0.1 percentage point from January to September.

　　Zhang Bo, chief analyst of 58 Anjuke Real Estate Research Institute, said that real estate regulation and control continued to be "steady and steady", and the cooling of real estate has become a market consensus. He believes that the state strictly controls the flow of funds to the real estate sector, and developers are facing financing difficulties. Accelerating the payment of sales has become the consensus of housing enterprises. Under the huge financial pressure, housing enterprises may further exchange prices for quantity and accelerate the return of sales funds.

　　"The real estate data released by the Bureau of Statistics from January to October shows that the overall property market is still at a high level, but ‘ Golden September and Silver 10 ’ Fever, a number of data growth slowed down, showing a gradual and stable trend. " Zhang Dawei, chief analyst of Zhongyuan Real Estate, believes that according to the current trend, although the national real estate sales will still set an annual historical record in 2018, the sales area is likely to be basically the same as that in 2017, and the property market is close to the turning point.

　　"From January to October, there were more than 400 real estate regulation and control in the country, which set a new historical record. The superimposed real estate credit policy was tightened, and investor control was obvious. At the same time, after housing prices continued to rise for several years, the number of buyers chasing high decreased and the investor’s enthusiasm decreased. " Zhang Dawei said.

　　Xinhua News Agency, Beijing, February 19 (Reporter Bai Ying) The online comedy film "Diary of Getting Rich" has been well received by experts since it was launched on the first day of the first month of the 12th. The film reflects the great changes of the motherland since the reform and opening up from the perspective of a nobody, and pays tribute to the builders and ordinary workers in the process of urbanization in Qian Qian.

　　The story of Making a Rich Diary spans nearly 30 years. It tells the story of two poor boys in Northeast China, Xiaobao (Song Xiaobao) and Second Brother (Sha Yi), who struggled hard in Shenzhen and experienced various setbacks and hardships. After getting to know Malu (Mary), Qi Xin worked together to raise an abandoned baby.

　　The protagonists in the story are all ordinary people. Xiaobao sells coolies and odd jobs on the construction site, his second brother is a driver who drives the boss, and Malu sells underwear in the market. Although their lives are full of difficulties, they all show an optimistic and open-minded attitude.

　　"They are the ordinary and real first generation ‘ Deep drift ’ Rooted in Shenzhen, we struggled hard, grew up with this city and realized our dreams here. The fate of the little people and the process of the great era merge and meet in the story. " Song Xiaobao, the film director, said.

　　Tian Weigang, a professor at Communication University of China, believes that the diary of making a fortune pays tribute to the builders and ordinary workers in the process of urbanization in Qian Qian by depicting the hard work of a group of small people. "They are both witnesses and founders of the times."

　　Both Xiao Bao and his second brother have dreams of making money, but they have no education and no resources. They have experienced setbacks such as losing their jobs, being beaten, adopting and abandoning their children, and being arrested for smuggling. Even at the end of the story, they did not really "make a fortune", but they gained relatives and feelings more important than material wealth.

　　Zhang Wei, executive vice president of China Film Criticism Society, said that the film is called "diary of making a fortune". In fact, the so-called "making a fortune" and the desire for wealth are a kind of embodiment and symbol that ordinary people yearn for a happy life in an era when materials are not developed enough. "Whether it is a stall vendor or a migrant worker on the construction site, the film depicts a group of people who are struggling for a better life in detail."

　　Zhang Yaxin, deputy director of the Art and Literature Museum of the Chinese Academy of Art, also affirmed the social significance and practical value of the diary of making a fortune: "The companionship, kindness and warmth of ordinary people after many hardships are full of more explosive and shocking positive energy. It makes the audience believe that the life experience we have and the most kind and simple emotions between people are the most precious wealth. I believe this is also the warmest revelation that this film wants to bring to everyone. "
