1953, China Academy of Sciences organized a delegation to go abroad, headed by scientist Qian Sanqiang, with members including Hua, Zhao Jiuzhang and Zhu Xian. In his spare time, Hua wrote a couplet: "The Three Strongests of Korea, Zhao and Wei". 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.

Personality assessment

As a master of contemporary science who grew up by himself, Mr. Hua is also a famous mathematician at home and abroad. He devoted his life to the research and development of mathematics, promoted and trained backward talents with the broad mind of scientists, and devoted himself to the popularization of popular science and applied mathematics with a high sense of historical responsibility, making contributions to the development of mathematical science and the modernization of the motherland.

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".
