The Qin government wiped out the six kingdoms and unified the world, and he has been the first emperor since he heard from some Confucian students that the ancient emperors had to go to Mount Tai to hold the Feng Zen Ceremony in person to be a virtuous king. Mencius also said that a new emperor who has won the world must be recognized by God for his virtue and accepted his sacrifice before he can be regarded as the true son of heaven. Qin Shihuang led the minister of culture and martial arts and a large group of idle Confucian students to Mount Tai. They stopped at the foot of Mount Tai to discuss how to hold the ceremony. According to the Confucian students, the so-called "Feng Zen" is to sacrifice the sky on the top of Mount Tai and sacrifice the land at the foot of Mount Tai. The former is called Feng, the latter is called Zen. However, the emperor on the top of Taishan Mountain on the sacrifice of the sky do not take the car, must not take the car, but also use the grass to wrap the wheels of the car, so as not to break the grass and wood on the mountain, only to express the respect for Mount Tai. The tyrant heard that such conditions, in a hurry, did not allow the Confucian students to participate in the sacrifice, and took his own cronies of ministers up the mountain. Along the place where the car was not well painted, he cut trees and cut grass and cut stones. He thought to himself, "I want to see the god of Mount Tai, what am I?" Qin Shihuang and a group of people went up Mount Tai, sacrificed the sky, and erected a large stone monument on the top of the mountain. Soon, the sky changed, the clouds rolled, and it was going to rain heavily. Some people said that when the god of Mount Tai was angry, there were dark clouds and rain, and the floods erupted, and people and animals were to be washed away. Qin Shihuang had a ghost in his heart, thinking that he had offended the god of the mountain, and he ran down the mountain with his legs, and a group of his men fled. The group had just run to Wusongting, only to hear a thunder, the rain fell on the ground. Qin Shihuang was used to raising his head. Xiu said that the mountain flood, the heavy rain would not stand, and he would be washed down the mountain. In a critical moment, I suddenly found a large pine tree on the side of the road. The great emperor, who was in a hurry to kneel before the tree, held his hands dead and hugged the trunk, and cried out for the tree god to bless. It was raining fast and it was harvesting fast, and it stopped soon after. Qin Shihuang really thought that the tree god was protecting, so he sealed the pine tree that saved him as "five doctors' pine"
