It is the first political, economic and cultural center at the starting point of Shu Road in the southern foot of the Qinling Mountains. It is known as "the important town of Qin and Shu" and "the gateway to northern Sichuan". According to legend, Emperor Xuanzong of the Tang Dynasty went to Shu to avoid the an-Shi Rebellion. Various states and counties greeted him here, calling it "the son of Heaven", hence the name "Chaotian", which extended to the meaning of "rising to Heaven". Chaotian has always been the government of Lizhou and Guangyuan (prefecture and county). After the founding of New China, it was under the jurisdiction of Guangyuan County. In 1989, with the approval of the State Council, Chaotian District of Guangyuan City was established. On September 25, 2018, he won the honorary title of "2018 e-commerce into rural comprehensive demonstration county" of the Ministry of Commerce. 2019 1
