What Lu Zhou managed to gain over the past few days were massive.
It was not just in academic, but more in the sense of social networking.
Lu Zhou met many people that he had read about in textbooks, newspapers, and articles. That feeling itself was extraordinary.
For example, Heim Brenzi, an academician of the French Academy of Sciences. Lu Zhou had read Brenzi's "Functional Analysis" textbook, in which Brenzi's explanation of the Sobolev space made a lasting impression on Lu Zhou.
This old gentleman from France was very funny and enthusiastic. Especially after he heard that Lu Zhou read his work, he was even friendlier toward Lu Zhou. He repeatedly said that if Lu Zhou ever went to France, he could look for him.
Brenzi had an interesting collection of manuscripts, including one from Euler.
In addition to this warm and cheerful old man, Lu Zhou also met the Chinese mathematics genius, Tao Zhexuan.
