Li Ruifu has been familiar with ancient Chinese characters in China since he was a child, and he is also proficient in English and industrial calligraphy. He is a famous professor of mathematics.

14 (1925) After graduating from middle school, I decided to study mathematics and be a famous teacher all my life. When I was studying in the Department of Mathematics of Nanjing Central University, I fell in love with astronomy again. I thought China's ancient astronomy was accurate, but there was no theoretical discussion, especially about the calculation of celestial bodies, the formation of the solar system and the operation of planets. Solid foundation in mathematics, self-study hard. When I was in the second grade, I wrote The Sun and the Moon, which was included in the Everything Library edited by Wang, and became one of the early theoretical astronomy works in China. When I was in the fourth grade, I wrote The Solar System, which was recognized as the most detailed description of the solar system in China at that time. He also published many papers on celestial bodies in Science magazine and Journal of Central University. After liberation, he has been the vice chairman of the Shanghai Astronomical Society.
