It is said that Qin Shihuang always had a premonition that in the near future, someone would rise up and replace him and become the new "Lord of the World." However, who is this person? Where does this person live?
Qin Shihuang himself could not answer these questions. Therefore, some sorcerers advised Qin Shihuang, saying that this person must live in a place with dragon veins and royal aura. As long as Qin Shihuang digs out the dragon veins and destroys the royal aura, no one will take away Qin Shihuang's world.
Qin Shihuang was very happy when he heard about this and asked the magician about the place in the world that had dragon veins and kingly energy. The sorcerer's answer at that time was Yunyang, also known as Danyang, which was a territory of the Chu State during the Spring and Autumn Period and the Warring States Period. According to historical records, Qin Shihuang led his officials on an eastward tour. When they passed through Danyang, the accompanying historians divined that Yunyang had "king energy". Qin Shihuang was afraid that an emperor would emerge from Danyang and seize his power, so he immediately issued an order to break the "feng shui" of Danyang. One of the "measures" was to change the county name of "Yunyang" with the "king spirit" to "Qu'a".
Of course, just changing the place name is not enough to destroy Danyang's royal aura. In 220 BC, Qin Shihuang built Chidao, centered on the capital Xianyang, extending in two directions to the southeast: one leads directly to the Yanqi region. , one leads directly to the Wu-Chu area. The road is large in scale, with a high and solid roadbed, fifty paces wide, and green pine trees planted every three feet along the road, which leads to the four-sided border area and unifies the tracks. Chidao promoted economic and cultural exchanges and development at that time. However, the main purpose of Qin Shihuang's construction of this section of Chidao was not that it was basically the Chidao in other places. The "Kuiji Chi Road" is winding when it passes through Danyang. This is why Qin Shihuang specially "straightened the road and made it curved" when building the Danyang Chi Road. That is to say, he deliberately made the straight road into a curve, which was to cut the dragon's veins and break the king's energy.
However, Qin Shihuang's luck did not seem to be very good. After his death, the Qin Dynasty not only enjoyed a very short period of time, but also Danyang did have an emperor in later generations. From this point of view, when Qin Shihuang dug the dragon veins of Danyang. , maybe something went wrong, otherwise, how could there be an emperor in future generations?
