Thirty-three years (214 B.C.) in Panyu, Qin Shihuang expanded Zhaotuo, king of South Vietnam, into a capital city (now Yuexiu Mountain, Xianggang Mountain area) ten years later. In April 2000, 600 square meters were excavated between Huifu East Road and Xihu Lake, and the ruins of wooden sluice gates in South Vietnam (south of the capital of South Vietnam) were found. Nearby, the ruins of Eastern Han Dynasty, Shuijing in Southern Dynasty, Tang Dynasty and Song Dynasty were also found. This is another important archaeological discovery after the discovery of the Nanyue Palace and the Palace Garden Site in the area of Zhongyou Street from 1974 to 1995.
