Taiping County in Dazhou is the predecessor of Wanyuan City today. History: "In the tenth year of Zhengde in Ming Dynasty (15 15), Taiping County was located in Li Taiping, dongxiang county, belonging to Dazhou, and was the capital of Kuizhou in the early Qing Dynasty. Yongzheng six years (1728), returned to Dazhou. In the seventh year of Jiaqing (1802), Taiping was promoted to county magistrate, directly under Sichuan East Road. In the second year of Qing Daoguang (1822), Chengkou Hall was set up, which belonged to Sui Dingfu, and Taiping still set up a county. " In the third year of the Republic of China (19 14), it was renamed Wanyuan county because it had the same name as Taiping county in Anhui province, that is, "there are thousands of ponds in the northeast of the county, from which much water from neighboring cities comes". 1July, 1993, with the approval of the State Council, Wanyuan County and Baisha Industrial and Agricultural Zone were abolished and Wanyuan City was merged.
Baisha River was built in the tenth year of Zhengde in Ming Dynasty (15 15), and Baisha Township was built in 1940. 1978 county-level Baisha industrial and agricultural demonstration zone was built, and 1979 was changed to Baisha industrial and agricultural zone. Now it's Baisha town.
