According to legend, the surname Li comes from the Yellow Emperor, and his ancestors are descendants of Zhuan Xu, the grandson of the Yellow Emperor. Hao Tao, an official in Dali, Yao Di, was in charge of justice and presided over the formulation of five kinds of punishments, which were called "five punishments" in history. It is said that he can also drive a unicorn named Ara. This monster is very spiritual and can distinguish good from evil. When you see a guilty person, there is a unicorn to hit, and you get angry when you tell a lie. With its help, Hao Tao never made mistakes in deciding cases and became a famous judge. Since then, his descendants have inherited their duties, including Li Yu, Xia and Shang, taking the official position as their surname and being called "Li". At the end of the Shang Dynasty, his descendant Sun was executed because he could not tolerate it. His wife, Qi and Shi, fled to the market together. On the way to escape, the mother and son were hungry, thirsty and without food, so they had to pick fruits from the plum trees on the roadside to satisfy their hunger, so as to save their lives. Later, Li Zheng gave birth to his long ancestor and became a doctor in Chen Guo. His descendants grew up slowly. To commemorate the fruit of the plum tree where our ancestors lived, we changed our surname from Li to Li.
