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.
