There are eight ways to fly stars in the sky (also known as the three schools). Among them, Kong Xuan Xing Fei School is divided into several factions. Jiang Dahong, known as the founder of Kong Xuan School in Qing Dynasty, advocated the movement of "Qi of Three Yuan and Nine Yuan" with the flying stars of Jiugong. There are six influential schools, namely impermanence school, southern Yunnan school, Suzhou school, Shangyu school, Xiangchu school and Guangdong school. In addition, there are Li, Wen Mingyuan, Gao Guanzhong, Dai Xilun, Zhao Luyuan and Wu. , have their own schools, more than one hundred schools. In modern times, the theory that Mr. Tan founded and guided the binary eight games is called Tan Xuanxue. Mr. Wang Tingzhi founded the Zhongzhou School. There are also Luo's mysterious gas, Miao's mysterious gas and so on. There are more than 100 primary schools in Kong Xuan School, and the main difference lies in the difference between flying stars and flying dragons.

Yang Gong's three-in-one geomantic omen: Yang Gong's geomantic omen inherited the theoretical essence of Guo Pu's "taking advantage of anger" in Jin Dynasty, paying special attention to the situation and paying attention to the kung fu of "seeking dragons for three years and selecting acupoints for ten years". Long Ge's five elements were "subverted" by "catching stars" (72 dragons), and the Shuang Shan in the sky was used to eliminate the sand and water. In the method of regulating qi, Yang Gong's geomantic omen pays attention to the qi of earthly branches, attaches importance to the intercourse of dragon water and yin and yang, focuses on the seventy-two dragons, and focuses on the three hexagrams of parents (that is, mud is different from earthquake), and advocates the trinity of dragon, water and direction, that is, the dragon is combined with water and hydrated, and requires the triple beads of dragon, water and direction. He also stressed that dragons and water must come from the prosperous side, and water must flow back to the grave.

The theory of immortality and the five elements of the Chinese zodiac is one of the main theoretical foundations of Yang Gong's geomantic omen. The trinity of Wang Sheng's tomb was first seen in Liu An's "Huai Nan Zi Tian Xun" in the Western Han Dynasty: "Wood is born in the sea, stronger than the foundation, and dies before, and all three are wood." Fire is born in yin, stronger than noon, and dies in deficiency, all of which are fire. Gold is born in three, stronger than one, and dies in ugliness. All three are gold. Water is stronger than Shen, and it is stronger than Zi. When you die in Chen, all three Chen are water. "

"Kun nonyl B, Wen Qu from scratch; Gen Bingxin, whose position is Lian Zhen; Xun Geng Gui, all Wu Qu; Dry Jiading, greedy wolves all the way ",that is to say, the sky board made in Shuang Shan. Shen Kun is in the same palace, Ren Zi is in the same palace, Yi Chen is in the same palace, and Wen Qu is Mercury, so Kun Renyi and Wen Qu are from the beginning; Genyin is in the same house, Bingwu is in the same house, Xinxu is in the same house, and Lian Zhen is Mars. Therefore, the root of Bing Xin is Lian Zhen; Xun is in the same palace, Geng Xu is in the same palace, and Gui Chou is in the same palace. It is Venus. Therefore, Xun Genggui is Wu Qu; Dry sea is the same palace, Jiamao is the same palace, Ding is different palace, and the wolf is wood. Therefore, Gan Jiading was greedy for wolves all the way.
