Judging from the administrative divisions of the Tang Dynasty, Chongzhou was the state capital of Hebei Province (yu zhou is the southeast of Daming in Hebei today), not Chongzhou under the jurisdiction of Sichuan today. Chongzhou today was called Zhou Shu in the Tang Dynasty. Wang Bo, a poet in the Tang Dynasty, wrote in Du Shaofu's Zhou Shu: "Know yourself and know yourself, and you will win every battle.". Chongzhou in the Tang Dynasty should be Changli County under the jurisdiction of Qinhuangdao City, Hebei Province today. . "Old Tang Dynasty Book Chongzhou Chapter" said: "In the five years of Wude, Chongzhou and Zhou Xian set up the governor of Raole County, and Xihan set up the governor of Mars State. One of the old counties, "Zhenguan" and "Changli" set up Beilizhou in two years, and sent Shi Yang Town to the northeast of Yingzhou. In eight years, it was changed to Chongzhou and Changli counties.
