The Chronicle of Xuanyuan said that when the emperor first divided the state boundaries, he asked Qingwuzi for advice. In Bao Pu Zi written by Ge Hong in Jin Dynasty, Wu Qinzi was described as a disciple of Peng Zu, the ancient birthday girl, who lived to be a hundred years old and then became an immortal.
However, later scholars believe that Qing Wu Zi came from the Han Dynasty, and it was recorded in Customs Tong and Old Tang Shu. It is said that Qing Wuzi was a relative of Han Dynasty and was good at burial. He has written three volumes of Qing Wu Zi, which is often quoted by later generations. According to textual research, the book "Five Children of Qing Dynasty in Hunan" which is now circulating is a work under the guise of name.
Why is Jiutian Xuan Nv called "the sacred bone of Feng Shui"?
According to legend, in the pre-Qin period, Lao Zi Li Er, the ancestor of Taoism, had two disciples. One is the fairy teacher of Guigu, whose common name is Wang Xu. One is Nine Days Xuan Nv, commonly known as Zhongjing. They are all proficient in Feng Shui. One day, Xuan Nv trudged eight hundred miles in nine days to Yanshan Mountain, and found a black dragon beside the black pool thousands of miles away. After following the black dragon into the black hole by the pool, I found the nine-day secret written on the ice wall, which is divided into three parts, the upper part is the secret passage, the middle part is the infernal affairs, and the lower part is the ground pulse passage.
The person who writes the Secret Passage is the person who has a great omen for the Secret Passage. The sky is surrounded by twenty-eight lodges as the meridian, four constellations in the southeast and northwest. "Humanism" is a way of interpersonal relationship, which includes all methods and strategies, art of war and martial arts. If you know a thing or two, you can be the emperor's teacher. The "ground pulse road" is the first dragon. The dragon is a mountain range and the breath of the earth. When the gas comes, it needs water to guide it, and when it stops, it needs water to limit it. It must be windless when it gathers, and it will disperse when there is wind. Because it is the way of the earth, it is called Feng Shui.
Xuan Nv after watching, carefully ponder, unknowingly suddenly enlighted. The ice wall gobbledygook helped Xuan Nv build a road for nine days, so Empress Xuan Nv was also called a Feng Shui nun. Those who learn this way will respect Xuan Nv for nine days as the ancestor of geomantic omen.
