Why is Xuzhou called Xuzhou? Is it because most people named Xu live there?

The name of Xuzhou has always been explained in different ways. "Taikang Diji" thinks that it got its name from Xu Qiu, and some people think that Jishui comes from the Yellow Sea "its air is wide and comfortable, and its nature is peaceful", so it is called Xuzhou. Liu Xi's "Release of Names": "Xu means Shu. The rustic atmosphere is soothing." It is believed that Xuzhou was named based on the soothing rustic atmosphere. In fact, these statements are meaningless. Xuzhou is named after Xu Fang, which is a famous ancient country to the north of the Huaihe River - Xu State. Xu Fang, known as Xu Yi in history, was an indigenous resident living in the Sishui River Basin. He had already established a country in the Shang Dynasty, named Xu Fang or Xu State. The Kingdom of Xu was very powerful by the time of King Yan. King Xu Yan once led the Nine Barbarians to attack Zongzhou, forcing King Mu of Zhou to recognize his status as suzerain in the Huaihe River Basin. Thirty-six countries from far and near submitted to him. The so-called Qunshu seen in "Spring and Autumn", such as Shu Liao, Shu Yong, Shu Jiu, Shu Gong, etc., are all important branches of Xu State. "Shu" and "Xu" are interchangeable characters. In the bronze inscriptions written by Xu, people often refer to "Xu" as "Shu" and "Shu" as "Xu". Xu State was still quite prosperous during the Spring and Autumn Period, and it continued to have wars with neighboring countries.

Located between Hai, Dai, Huai, and Ji, it was the settlement area of ??Dongyi at that time. Xuyi occupied a leading position among Dongyi. It is natural that Xuzhou was named after Xu State
