What is the focus of argument between Wang Wan and Li Si?

The focus of argument between Wang Wan and Li Si is that Li Si demands the county system, while Wang Wan demands the enfeoffment system. The county system is an ancient centralization of authority in the local political power, which was founded in the Spring and Autumn Period and the Warring States Period, and became a local political system after Qin and Han Dynasties after Qin Shihuang's reform.

Li Si was a native of Shangcai (now Lisilou Village, Lugang Township, Shangcai County, Henan Province), a famous politician, writer and calligrapher in the Qin Dynasty. After the death of the first emperor, Reese and Zhao Gao forced Fu Su to commit suicide and made Hu Hai emperor. After the peasant uprising broke out at the end of Qin dynasty, he suggested that II should be more legal, implement "the art of supervising responsibility" and strengthen monarchical power.
