I want to know the origin of the naming of Qianjiang in Chongqing.

Qianjiang in Sui Dynasty is not called Qianjiang, but Shicheng County, which belongs to Badong County. The county seat is now on the dam of Bai Zhou County, where the ancient city of Shicheng in Bai Zhou is about to be restored. It is near the Apeng River, which is a distribution center for salt and so on. Convenient transportation, it belonged to the rich area at that time. During the Tang and Five Dynasties, Qianjiang moved to the present Union Town (east of the city). I don't know if it has something to do with wanting to get close to Wujiang, or is it the civil strife of the toast? It was named at that time, because Wujiang was called Qianjiang at that time, so it was simply called Qianjiang at that time. At this time, Qianjiang belongs to Guizhou (now Yushan Town, Pengshui County-a very famous place in the Tang Dynasty), which is the largest salt distribution center in the whole Sichuan Basin and one of the eight famous people in the Tang Dynasty. I forgot what it was. At that time, it was the cultural, military, political and economic center of the whole border of Hubei, Sichuan, Guizhou and Hunan. It is also the birthplace of Qianzhong culture, one of the earliest cultures in Bashu, probably around the Spring and Autumn Period and the Warring States Period. The money in Qianjiang is more than 800 years earlier than that in Guizhou. Moreover, according to the controversial point of view, the story of Guizhou donkey took place in Yushan (Guizhou). At that time, Pengshui and other places also became places where prisoners were exiled. Famous exiles include Sun Chang Wuji and Huang Tingjian. Qianjiang has not changed its name since then, but it was changed to "Qian Wanpeng" in the Qing Dynasty, belonging to Youyang House in Chongqing. During the Republic of China, it belonged to the eighth administrative region of Sichuan Province (Youyang). * * * and the founding of the People's Republic of China began to belong to Youyang area, and then to Fuling area. In 88, Shizhu, Pengshui, Qianjiang, Youyang and Xiushan were established, and Qianjiang Special Zone was established, which is the youngest area in * * * and the whole country. As for when Wujiang River will be diverted to Qianjiang, it is also something that needs to be investigated. In ancient times, many rivers were diverted. For example, the former Yellow River estuary was not in Dongying, Shandong, but near Lianyungang, Jiangsu.
