In this era, though the political situation is chaotic, thoughts remain relatively active, with the academic trend of speculation accelerating the rapid development of mathematics. Works like "Annotations on The Nine Chapters on the Mathematical Art" and "The Island Mathematical Classic" have astounded the world.

Being able to write does not necessarily mean having advanced knowledge in mathematics.
It just so happens that Yan Buxi of Qi Country is one such individual.
