Metaphysics, what is the "Qi of the Son of Heaven"?

Since Qin Shihuang established the first unified, multi-ethnic and autocratic centralized state in the history of China. It has been more than 2 100 years since Qin Shihuang came to Xuan Tong, and more than 200 emperors have appeared. For more than 2000 years, wars have been going on because of land disputes, ethnic wars, foreign resistance and the struggle for the throne within the royal family. In order to ensure their long-term stability, the emperors not only straightened out their political affairs and stabilized the people's hearts, but also strengthened the construction of the Ministry of War. The emperor also believed in divination and geomantic omen. According to the Book of Changes, "The king of Fugu is the king of the world. He looked up at the sky, bowed his head, looked at the ground, looked at the articles of birds and beasts, and merged with the ground. " Feng Shui in China was in its infancy in the pre-Qin period, its development in the Wei and Jin dynasties, its peak in the Southern Dynasties and its flooding in the Tang and Song Dynasties. During the Anshi Rebellion in the Tang Dynasty, he was very cautious about Feng Shui. He chose Long Mai to take advantage of the mountains and rivers generated by heaven and earth, take himself as the East, and emphasize the cooperation of dragons, caves and sand and water. Because the bodies of children and grandchildren are part of the inheritance of parents' ancestors, if the parents' bones can be preserved by the "dragon gods" of mountains and rivers generated by heaven and earth, future generations will be sheltered and the mountains and rivers will last forever, thus carrying forward the vast. Therefore, in the Zhenguan period of the Tang Dynasty, another Yuan Tiangang who predicted bad luck and surveyed Feng Shui broke Long Mai's theory. One day, Yuan Tiangang told Emperor Taizong that there was a "spirit of the son of heaven" somewhere. The so-called "spirit of the son of heaven" means that a new emperor may be born somewhere, if a new emperor is born. Don't you want to compete with Li Shimin for the world? That will cause a great confusion. So Emperor Taizong sent Yuan Tiangang to measure "Wang Qi" to break Long Mai. According to records, when cutting the stone vein, the water on the broken rock is like blood. Therefore, people call it "sawing mountain pass". China Feng Shui is still used in some parts of China.

According to legend, during the Hongwu period of the Ming Dynasty, Liu Bowen, the adviser of Zhu Yuanzhang, discovered a dragon vein not far from Gannan Metallurgical Pass in Gansu. In order to consolidate Zhu Yuanzhang's mountains and rivers, Liu Bowen came here and broke the emperor's Long Mai.
