This is just a small episode in the preparatory work, in addition to preparing the speech, publishing the paper on the arXiv website, browsing the latest articles on the Poincaré conjecture, and learning cutting-edge physics, Lu Qiujian has another job of preparing the translation with the simultaneous interpreters convened by Beijing Normal University.

With the passage of time, the venue of the conference was prepared, the translation of the speeches was verified, the training of the conference volunteers was successfully completed, the list of invited leaders was finalized, and most importantly, the mathematicians who were invited to the conference started their own itinerary, from New York, from Los Angeles, from London, from Humboldt, from Moscow, from Tokyo, from Paris, from the Pearl from the gates of various world-renowned universities and research institutes, rushed to the nearest airport, and flew to the capital of China!

The logistics staff and volunteers of Beijing Normal University also took action to prepare for the arrival of these math masters at the airport, at the railway station, and at the entrance of the school.

The mathematics department simply suspended classes for a week and gathered all the students to arrange for various points to cooperate with the school's work, and Lu Qiujian's roommates, Xu Ye and Li Yincheng, were sent to the hotel door to do reception work.

"People are comfortably drinking tea in the hotel while blowing the air conditioner! Let's just stay under the sun and prepare for the reception! It's so hard!" Xu Ye looked at the hotel with envy, in order to better communicate with these mathematicians, the school arranged Lu Qiujian here.

"Besides, it's not without benefit for us to stay here, in case we talk to that master, it's convenient to apply for study abroad at that time!" Li Yincheng looked at it more far-reaching, "It would be nice if I could meet Professor Atia from Cambridge in a while! Chat with him and ask for an email address or something! Maybe I will be taken to England by him!"

"You can still see it! I said, how can I talk to these people, the work is not arranged for the senior or the third year, it turns out that the school has already planned!" Xu Ye suddenly realized, only to understand that this is an opportunity given by the school, "Then I will go and say hello to Professor Jean-Pierre Serre of the Collège de France!"

"Who are you talking about?" asked the girl who borrowed it from the Chinese Academy on the side, no way, there are too few girls in the mathematics department. There were no two good-looking girls at the reception, and they were really not good-looking, so I had to borrow them from the foreign language department with many beautiful women.

"Xiao Yue, what we just said is the authority of mathematicians!" Xu Ye hurriedly began to answer her question when he had the rare opportunity to talk to the girl again, "Michael Francis Attia is the dean of Trinity College, Cambridge, and has made outstanding contributions to the fields of topological K theory, Li Qun representation, and algebraic geometry related to gauge fields, and won the Fields Medal in '66. Jean-Pierre Serre is a professor at the Collège de France, whose main contributions are topology, algebraic geometry and number theory, and winner of the Fields Medal in '54! Oh, yes. The Fields Medal is the highest award in our mathematical community, and it is comparable to the status of the Nobel Prize in physics, chemistry and medicine!"

"Oh~ I seem to understand a little! they are all top figures in the industry!" The girl known as Xiaoyue asked again, "Then they came to Beijing Normal University to participate in this Lu Qiujian's report meeting?"

"Yes, Qiu Jian solved the Poincaré conjecture in the Seven Mathematical Puzzles, so these people are here!" Xu Ye's tone was full of endless envy, how good it would be if he was the one who made the result!

"I heard that he is only 20 this year, and he is still playing great basketball, and he almost went to the NBA?" the little girl asked a series of questions, and her eyes were full of stars! Xu Ye was very congested when she saw it.

Fortunately, his depression didn't last long, so Li Yincheng hurriedly patted him on the shoulder, "Stand up, just called and said that the car will come soon!"

Xu Ye hurriedly turned around and stood up. whispered, "I don't know who is here this time?"

As he spoke, Professor Zhang and the others also came down and waited at the door for five minutes. The car stopped at the entrance of the hotel, and a man about fifty years old stepped out of the car, and Professor Zhang and Lu Qiujian hurriedly greeted him, "Professor Friedman." Hello and welcome to Huaguo!"

During their greetings, Xu Ye and Li Yincheng hurriedly went up to help Friedman take off his luggage. They followed them and sent them to the hotel.

"Wow, that's Lu Qiujian!I'm afraid he's more than one meter eighty-five!" Xiao Yue asked after returning to the door, "Who was that just now?"

Michelle Friedman, a member of the Academy of Sciences and a professor at the University of California, was the recipient of '86. This time, Xu also directly omitted the name of the Fields Medal.

Then they welcomed Yau Chengtong from Pearl Chinese University, neon mathematician Ito Kiyoshi from the University of Minnesota, Chio Sato from Neon Kyoto University, Arnaud from the University of Paris, Harry Furstenberg from the Hebrew University of Jerusalem, and Jürgen Moser from the Zurich Federal High School.

At five o'clock in the afternoon, the most exciting moment finally arrived: a bus slowly stopped at the door, the door opened, and Pierre-René-deligne, who was nearly sixty years old and half bald, respectfully helped an old man older than him to slowly step out of the car.

"Oh my God, why is he here!" Xu Ye and Li Yincheng's eyes suddenly widened, trembling with excitement, they could hardly help themselves, so they hurriedly went up to help them send their luggage upstairs.

"Isn't this man amazing? Why wasn't he so excited to see you just now?" seemed to her, and there didn't seem to be anything special about the man just now, except that he was older.

"That's Grothendieck! I didn't expect him to come out after retiring for so long!" said Xu Ye while waving his arms excitedly, even though Xu Ye had not fully recovered yet, Let me tell you this, in the entire history of mathematics, the mathematicians of ancient Greece were the most influential with Euclid, Archimedes and Diophant; in the first half of the 17th century, Descartes and Fermat, and in the second half, Newton and Leibniz were juxtaposed, from the later development of history, Leibniz had a greater influence on mathematics, but Newton had a greater influence on physics; in the first half of the 18th century, Euler, from the end of the 18th century to the first half of the 19th century, Gauss, and in the second half of the 19th century, Riemann and Poincaré were tied! By the first half of the 20th century belonged to Hilbert, and the second half was Alexander Grothendiek!" )
