1953, the Academy of Sciences organized a delegation to go abroad, headed by the famous scientist Qian Sanqiang. Members include Hua, Zhao Jiuzhang and Zhu Xian. In his spare time, Hua wrote a couplet: "The top three are Korea, Zhao and Wei", seeking this couplet. ?

The "top three" here refers to Korea, Zhao and Wei San during the Warring States Period, but it implies the name of the head of the delegation, Comrade Qian Sanqiang, which not only solves the traditional difficulty of the couplet of numbers and numbers, but also requires the name of another scientist to be embedded in the bottom couplet. After a while, when Hua saw that everyone had no bottom line, he revealed his bottom line: "Hook, strand and string are nine chapters."

Nine Chapters is a famous mathematical work in ancient China. However, the "Nine Chapters" here happen to be the name of another member of the delegation-atmospheric physicist Zhao Jiuzhang. Hua's wonderful pair made the audience fall for it.

Hua's contribution to the development of mathematics in China is known as "the father of modern mathematics in China", "the god of mathematics in China" and "the people's mathematician".

He is a famous mathematician in the world. His name ranks with a few classic mathematicians in famous museums such as Smithsonian Museum and Chicago Museum of Science and Technology, and is listed as "one of the 88 great mathematicians in Chicago Museum of Science and Technology today".
