In the history of China, there have been many incidents of digging ancestral graves. Grave robbers not only covet the treasures in the tomb, but also have a purpose, that is, to destroy the geomantic omen and let the family whose ancestral graves were dug completely perish. It can be said that in the past, both princes and ordinary people believed in the existence of feng shui in tombs, so most emperors would look around for their burial places after their death. Most of them think that the prosperity of a family or a dynasty is largely related to the feng shui of the mausoleum. For emperors, if their tombs were built on the Long Mai, they could keep their throne for generations. In addition to choosing a feng shui treasure house for your grave, it is also considered beneficial to future generations. In Feng Shui, there is also a saying that a person occupies a grave for good luck.
During the Spring and Autumn Period and the Warring States Period, Danyang was the territory of Chu State. In 222 BC, Qin Shihuang pacified the Jiangnan area of Chu and established Huiji County, which now governs southeastern Jiangsu and eastern Zhejiang. Danyang was also changed to Yunyang County. It is such a small Yunyang county. I don't know how much effort Qin Shihuang spent, and even destroyed the "king" of this place at any cost. It turns out that Qin Shihuang did this for a reason. At the beginning, he traveled eastward through Danyang realm and followed the historian to predict that Yunyang had a "king". So Qin Shihuang was very afraid that there would be an emperor in Danyang to compete for his country, so he immediately ordered the destruction of Danyang's "Feng Shui". One of the "measures" is to change the name of Yunyang County from "Wang Qi" to "Qua". The second move is to change the section of Huijichi Road passing through Danyang into a bend, that is, to deliberately turn the straight road into a bend, and its purpose is also to break the "king" of Danyang.
So why did Qin Shihuang have such a profound study of Feng Shui? Does he have any superior people around him? Or is he a feng shui master himself? Or is there some kind of science and technology juexue that has long been lost in the pre-Qin period? We can't know these things today, but we can know that Feng Shui may not be reliable. Qin Shihuang deliberately destroyed the geomantic omen in Jinling, built a mausoleum and built the Great Wall. Finally, Qin Sanshi died, and his dream for generations was not realized.
