After a few idle sentences, Dong Qinqin forgot Wei Dongsheng's identity as the chairman of the board of directors in the Spring and Autumn Search, and gradually regarded Wei Dongsheng as Yan Hang's senior because of age factors, and asked in a consultative tone: "During the interview, the question of the random probability generator is 'Knowing a random probability generator, the probability of producing 1 is 0.2, and the probability of generating 0 is 0.8. Asked how to use this generator to construct a new generator with a probability of 0 and 1 of 0.5, I lost points for this question. I expanded the random number to 2 digits: 00, 01, 10, 11, but ignored that 01 and 10 were already equal probabilities, resulting in unnecessary bloat in my solution. The interviewer's final comment was that in terms of mathematical foundations, I have a very good grasp of calculus and linear algebra, while probability theory and discrete mathematics are lacking, and I hope to make up for the shortcomings as soon as possible. When I was leaving, the interviewer enthusiastically recommended a set of textbooks for me to study probability and statistics, discrete mathematics, graph theory, and group theory. I would like to ask, is search engine development really inseparable from these? ”

227th shaved head

Looking back at the list of China's top 500 companies in terms of turnover in 2008, The Spring and Autumn Group ranked 176th with 36.03 billion yuan, compared with last year's 347th, an extremely high increase; Zhixing Group ranked 69th with 89.26 billion yuan, and it has just emerged from the Zhiyu Group in less than two years, and it has become one of the top 100 enterprises in China; Zhuwei Group ranked 52nd with 113.04 billion yuan, compared with last year's 104th, the improvement is also very high; Zhiyu Group ranked 16th with 217.71 billion yuan; compared with last year's 60th, there is also a qualitative leap.

In 2009, Zhiyu Group ranked 16th among the top 500 in China.

In front of Zhiyu Group, they are Huaguo Petrochemical, Huaguo Petroleum and Natural Gas, State Grid, Industrial and Commercial Bank of China, Huaguo Mobile, China Construction Bank, Life Insurance, Huaguo Bank, Agricultural Bank of China, Sinochem, China Southern Power Grid, Baosteel, China Railway, Huaguo Railway Construction, Huaguo Telecom, all of which are administrative monopolies with Chinese prefixes. Pulling down further, Huaguo CNOOC, which ranks 17th, Huaguo COSCO, which ranks 18th, and COFCO, which ranks 19th, are also Chinese bigwigs.

Zhiyu's honor is not limited to the top 500 in China. In the 2009 Fortune Global 500 list, a total of 44 companies from Greater China were on the list, including 3 in Xiangjiang, 6 in Wanwan and 35 in mainland China. Focusing on the mainland, there are only two private companies on the list, one is Jiangsu Shagang, which ranks 445th, and the other is the wisdom universe (Zhiyu), which ranks 265th. Zhiyu Group made its first appearance on the list of Fortune magazine's top 500 companies and rushed to the top 300, who dares to ignore its existence?

The glory of Zhiyu Group is so bright.

The richest man in China for three years, the world's top 500 companies for seven years, Wei Dongsheng's career is so successful.

Even Quantum Rose's four-dimensional space also took advantage of the rise of web games and mobile games to brush the annual turnover of 780 million yuan in 2008, indirectly bringing a net profit of 58.05 million yuan. Although the amount is small, it is the first profit of the four-dimensional space, which symbolizes that it has gone through the stage of burning money to open up the market.

Wei Dongsheng in the eyes of the people is by no means a pure entrepreneur.

From 2002 to 2009, the children of other families had just been promoted from a junior high school graduate to a college graduate, but Wei Dongsheng had already created a Fortune 500 company, two Chinese top 100 companies, and one Chinese top 500 company. It seems that the Spring and Autumn Group, which has the least revenue, has the Spring and Autumn Network, which dominates the Chinese online game market, and the Spring and Autumn Search, which has a market value of 270.4 billion yuan.

If Wei Dongsheng had studied at a normal pace, he would have graduated from the college entrance examination in 2005 with a bachelor's degree in 2009.

Wei Dongsheng is in the same session as Ji Susu, and Qiu Ye, Dong Qinqin, and Deng Yu are also in the same session. In the eyes of Deng Yu and other peers, Wei Dongsheng is not only a child of other people's families, but also an idol of the times: Wei Dongsheng is a miracle of the rapid development of China's Internet enterprises, a symbol of the great rejuvenation of the Chinese nation in catching up with Japan and surpassing Germany, and a declaration of "a strong youth is a strong country" as a new force represented by the post-80s and post-90s......

Hearing that he was fortunate to see Wei Dongsheng at close range, Deng Yu suddenly became excited: "Wei Dongsheng came to inspect us personally?" ”

Dong Qinqin was relatively calm, and complained about Deng Yu and said, "What are you inspecting? People are old classmates. ”

Deng Yu retorted: "That's also Wei Dongsheng." ”

Although he clearly understood that Wei Dongsheng's real mind might just be to meet his old classmates, Deng Yu still couldn't control his excitement, and even behaved a little abnormally.

In front of the main entrance of the Spring and Autumn Search Building is the Spring and Autumn Ninth Street, and the Spring and Autumn Ninth Street walks west for five or six hundred meters, that is, the Spring and Autumn Third Scientific Research Institute, which is very close to each other. Ji Susu, Dong Qinqin, Deng Yu and other three people came to the Third Scientific Research Institute of Spring and Autumn and quickly found Building 4 by referring to the mobile phone application Spring and Autumn Map.

Approaching Building 4, he found a bald man standing alone at the door, and Ji Susu suddenly sighed.

Deng Yu followed the prestige, and also sighed suspiciously: "The person at the door is a bit like Wei Dongsheng." ”

Dong Qinqin questioned: "Remember that Wei Dongsheng is not bald." ”

Ji Susu distanced herself from her companion and walked quickly towards the bald man.

Yu Guang caught a glimpse of Ji Susu, and the bald man also walked towards Ji Susu at a normal pace: "The formalities are completed?" ”

Ji Susu's eyes suddenly widened and exclaimed: "It's really you?" ”

The bald man smiled and said, "Who else." ”

Ji Susu and Deng Yu were not mistaken, the man with shaved hair and a bright head was Wei Dongsheng.

Confirming that it was really Wei Dongsheng, Ji Susu couldn't help but laugh without vividly: "Why did you shave your head?" ”

Wei Dongsheng was speechless: "Isn't it funny?" ”

Ji Susu stopped laughing, and immediately asked with concern: "You won't have cancer like Jobs, right?" ”

In August 2004, Steve Jobs disclosed to Apple employees that he had been diagnosed with pancreatic cancer. At the beginning of 2009, Steve Jobs temporarily left the CEO position due to health problems, and his health became a hot topic again. Jobs's health news and the popularization of pancreatic cancer are the background of the times in the first half of 2009, Ji Susu is ignorant and passively understands some cancer knowledge, and when he sees his shaved head, he can't help but wonder if Wei Dongsheng has cancer and is undergoing chemotherapy.

Wei Dongsheng denied it in time: "There is no such thing. ”

Ji Susu: "Really? ”

Wei Dongsheng: "Not really. ”

Ji Susu didn't insist: "Okay, I believe you." But why did you shave your head? ”

Wei Dongsheng: "Research needs, I'll talk to you later." ”

Ji Susu: "Hmm. ”

Wei Dongsheng then entertained Dong Qinqin and Deng Yu: "You are all Ji Susu's classmates? ”

Although they are of the same age, Wei Dongsheng's career achievements have brought great psychological pressure to the graduates. Dong Qinqin was flattered, and hurriedly replied: "I am Su Su's roommate Dong Qinqin, I ...... I've seen you before. ”

Deng Yu also misexplained some unnecessary details: "I am not from Yanhang, I graduated from Yanjing Post and Telecommunications. ”

Wei Dongsheng didn't have the heart to ask them about the trivial details, and led them to the reception room: "Come in first." ”

Walking and climbing the stairwell, Ji Susu introduced each other as an intermediary, and told Dong Qinqin and Deng Yu some interesting things about Wei Dongsheng's high school days; and Wei Dongsheng complained about some of the troubles between classmates, joking that Dong was diligent and greedy for money before he was willing to come to Panyang, and teasing Deng Yu for being a reincarnation, and chasing her classmate Qiu can also chase Panyang. Dong Qinqin felt embarrassed and secretly pinched Ji Susu's arm to punish him; Deng Yu's face was also flushed with shame, and he retorted repeatedly: "I didn't." ”

However, they misunderstood Ji Susu.

Ji Susu knows Wei Dongsheng's attitude towards things, on the one hand, public to public, private to private, and will not damage the interests of the Spring and Autumn Group because of his personal feelings; On the other hand, Wei Dongsheng also understands the truth that "if the water is clear, there will be no fish, and if people are observant, there will be no fugitives", and he will not simply and rudely refuse all forms of going through the back door of relationships.

For example, if a job requires an employee with 100 to 120 points of competency, due to the limitations of task assignment and the limitations of existing management technology, many employees with 110 or even 130 points of competency may not be able to be assigned to the position. In this case, an acquaintance asked Wei Dongsheng to take the back door to take a shortcut, if the ability of the person who took the back door was less than the minimum 100 points, Wei Dongsheng would inevitably refuse ruthlessly or euphemistically suggest to be transferred to other positions; If the ability to go through the back door exceeds 100 points, Wei Dongsheng will carefully consider the network request and allow the person who goes through the back door to get the position.

Ji Susu complained about the troubles to Wei Dongsheng and euphemistically explained to Wei Dongsheng the friendship between her, Dong Qinqin and Deng Yu, and hoped that Wei Dongsheng would provide convenience within the scope of his ability.

Wei Dongsheng understood the meaning of Ji Susu's words.

Wei Dong also understood Ji Susu's request. After all, Panyang City is a small inland city that lacks historical heritage, and for the time being, it is the best choice for fresh graduates such as Dong Qinqin and Deng Yu to stay in Yanjing. Dong Qinqin, Deng Yu and other classmates and friends are willing to follow Ji Susu to Panyang because they believe in Ji Susu's words, and Ji Susu feels obligated to take care of them, at least the future prospects cannot be too far behind the classmates who stayed in Yanjing.

Ji Susu worked hard to introduce talents for the Panyang City Branch, and Wei Dongsheng couldn't let her be cold.

Wei Dongsheng then talked about career development planning with Dong Qinqin and Deng Yu as a person from the past.

After a few idle sentences, Dong Qinqin forgot Wei Dongsheng's identity as the chairman of the board of directors in the Spring and Autumn Search, and gradually regarded Wei Dongsheng as Yan Hang's senior because of age factors, and asked in a consultative tone: "During the interview, the question of the random probability generator is 'Knowing a random probability generator, the probability of producing 1 is 0.2, and the probability of generating 0 is 0.8. Asked how to use this generator to construct a new generator with a probability of 0 and 1 of 0.5, I lost points for this question. I expanded the random number to 2 digits: 00, 01, 10, 11, but ignored that 01 and 10 were already equal probabilities, resulting in unnecessary bloat in my solution. The interviewer's final comment was that in terms of mathematical foundations, I have a very good grasp of calculus and linear algebra, while probability theory and discrete mathematics are lacking, and I hope to make up for the shortcomings as soon as possible. When I was leaving, the interviewer enthusiastically recommended a set of textbooks for me to study probability and statistics, discrete mathematics, graph theory, and group theory. I would like to ask, is search engine development really inseparable from these? ”

Wei Dongsheng first briefly introduced his views: "As far as I am concerned, I divide programmer work into three categories, the first category is structural work; The second category is efficiency work; The third category is logical work. Structural work, such as HTML designing web pages, does not require a high level of mathematical ability; Efficiency work and logical work are the abstraction of specific problems into mathematical problems. Early efficiency problems often relied on discrete mathematics, and now efficiency problems are more accustomed to applying graph theory. ”

Wei Dongsheng immediately added a positive answer: "The Spring and Autumn search engine is at the forefront of the times, and it needs more efficient work and logical work, and every algorithm innovation relies on a deep mathematical foundation. If you are willing to climb the peak in the field of search engine research and development, probability and statistics, discrete mathematics, graph theory, and group theory are all necessary to learn and learn well. ”

Dong Qinqin doubted: "Is it really promising?" ”

Wei Dongsheng misunderstood this promising question about whether there was a future in search engine research and development, and asked rhetorically: "What do you think?" ”

Ji Susu understood Dong Qinqin's character, and corrected and reminded Wei Dongsheng in time: "Her future is 'money', and I want to ask you if you can make a lot of money by developing a search engine." ”
