Whose qualities did Hua and Chen Jingrun praise in Stardust?
Stardust praised Hua's ability to correct mistakes and discover talents, and also praised Chen Jingrun's ability to put forward his own opinions.

A speck of dust on the star is a text in the sixth grade Chinese textbook. The asterisk refers to the theory of heap primes written by Hua, and the spot refers to a calculation error in the book.

This article tells the story of a young teacher in an ordinary middle school, Chen Jingrun, who wrote a wrong letter to China. Hua also admitted his mistakes and found a rare talent from them.

1957 10 Due to the appreciation of Professor Hua, Chen Jingrun was transferred to the Institute of Mathematics of China Academy of Sciences. 1973 published a detailed proof of (1+2), which is recognized as a great contribution to the study of Goldbach's conjecture.

A speck of dust on the star:

That was at the Beijing Mathematics Seminar.

One day, the famous mathematician Hua received a letter from a young teacher in an ordinary middle school. The main idea of the letter is: I read your book "On Stacked Prime Numbers" and found it well written. However, after repeated accounting, it was found that there were calculation errors. It's like a speck of dust on a star. I hope you can correct it.

Hua read the letter and opened the book. Another calculation, really wrong. He was full of praise: "Great. His opinion is completely correct. He has a high talent. "

Hua read the letter at the mathematical research meeting and invited the young people who wrote it to attend the meeting. The young man was Chen Jingrun, and later he became a famous mathematician. In this way, Hua found a rare talent from his own mistakes.
