It was Fan Li, a great statesman of Yue State in the Spring and Autumn Period. When the State of Yue was destroyed by the State of Wu, it was he who put forward the plan for the restoration of the State of Wu, and accompanied Gou Jian, the king of Yue, to be a slave in the State of Wu, and tried every means to get Gou Jian back to China, becoming the first counselor to help Gou Jian destroy Wu, and worshiping the general.
However, when Gou Jian restored the country, he realized that Gou Jian was a man who could share weal and woe, but could not share weal and woe, so he bravely retired and resolutely gave up his official position. First, he went to Qi State and changed his name to Ziyi. However, people in the state of Qi knew that he had good moral character and high talent, so they asked him to be the prime minister. Because he had decided to retire to the forest, he resigned soon. He settled in Tao, the commercial center at that time (now Dingtao County, Shandong Province), calling himself "Zhugong", and people called him.
