Lóngchuān
Longchuan is an ancient county on the upper Dong River. Tradition associates its old seat with Zhao Tuo, a Qin official who became ruler of Nanyue. A well and the site of his former residence preserved his memory in the town. The residence site became Guangxiao Temple under the Song and was repaired several times during the Ming and Qing. A shrine to the Nanyue king also stood near the county offices. These places kept the story of Zhao Tuo alive in a town that remained the county's administrative centre for centuries.
