In order to suppress the "Tian Zi Qi" in the southeast and destroy the geomantic omen here, Ying Zheng diverted the "Longzangpu" water flow in the southern suburbs of Nanjing at that time, and the specific location was in Fangshan Shilian, Jiangning District, Nanjing today. I have been to this place, and there are indeed traces of human excavation, but it was not left by Qin Shihuang's destruction of Nanjing Feng Shui, so I can't verify it. But since then, it has left a romantic river with rouge-Qinhuai River. Ying Zheng ordered a Taoist priest and a guest, and asked him for the elixir of life. So Ying Zheng is the most superstitious emperor in China history.
