Liu Hui, a mathematician and geometrician in Wei and Jin Dynasties, was a person who demonstrated mathematical propositions by logical reasoning in the history of China, and was called "Newton in the history of Chinese mathematics". After Liu Hui's death, Song Huizong added a title of "male" to him. In ancient times after his death, Liu Hui was often chased by his old hometown, so Liu Hui was called "Duke of Wei".

Liu Hui's achievements:
The mathematical knowledge of the whole Qin and Han Dynasties, including the famous Nine Chapters Arithmetic, was sorted out, perfected and annotated, which laid the overall framework of ancient mathematics in China. Liu Hui's contribution to mathematics is mainly to summarize the overall calculation framework of linear algebra.
It is divided into the following three aspects: first, the algorithm of simplifying complex fraction is expounded; Secondly, the existence of irrational roots is demonstrated; Thirdly, the unified theoretical basis of number sum formula operation is established, and the linear equations are solved by mutual multiplication and elimination. Liu Hui's main works are: Nine Chapters of Arithmetic Notes (volume 10); The weight difference (1) was renamed as island calculation in the Tang Dynasty.
