Wang Heng in the Ming Dynasty wrote in Lu Cong, Qing Yan: "The selection of land began in Shanxi and Guo Pu ... Later generations divided it into two factions ... saying that Jiangxi's method originated from Xie Ziyi in the Tang Dynasty, and they were particularly good at it. It refers to the main emotion, what role it plays, that is, what it stops at, with directivity, especially the collocation of sand and water in the dragon cave, regardless of other constraints. There is no respect in this river. "
A Qing Ding Ruipu's "Feng Shui Puzzlement": "The art of Feng Shui can't tell the position of the situation. Those who talk about the situation are now called mountains; The person who spoke this position is now called Li Qi. Tang and Song poets have their own sects. " Although the theoretical core of China's geomantic omen is "the unity of heaven and earth", "the coexistence of five elements" and "the balance of yin and yang", China's geomantic omen has formed many factions in the long years, which are divided into two theoretical schools in later generations, which are not contradictory to each other.
Environment School (Luantou School)
Originated in Jiangxi, it is also called Luantou School, Luanshan School, Xingfa School or Jiangxi School, and can be subdivided into Big Luantou School and Small Luantou School. Chaos Head focuses on the beauty of mountains and rivers and the choice of natural environment outside the building. The main operating methods are "Xiangtu Water Product Method" and "Surrounding Mountains and Rivers Method". Its theory is five classic geographical disciplines, such as "negative yin embraces yang", "water around the mountain is bound to be angry", "seeking dragons" (geographical situation of the main mountain range-general environment), "sand inspection" (soil data-agriculture), "acupuncture" (finding the main area), "observing water" (water source and stagnant water) and "orientation". Xiaoloutou advocates building a house or choosing a house with the back of the mountain, facing the sun, facing the water and facing the mountain.
Belief in art and mathematics (rational style)
The rational style advocates that "people stand because of houses, houses exist because of people, and people and houses help each other and feel the world". The main theory comes from eight diagrams and astrology, and it is about "yin and yang, five elements, branches and leaves, eight diagrams, nine palaces, etc." . Pay attention to the orientation and layout. The main operation method is to choose the best location and moving line of the house according to the hospital transportation. Shape method, logic method, Japanese method and auxiliary truth method are the basic methods to determine the location, architecture and decoration of a city. The main techniques are "Nine Palaces and Eight Diagrams" and "Twelve Earthly Branches".
Flying star method, connecting heaven and earth, people and time and space, using the "geomantic compass" integrated with time and space to choose a house for building. The house was built in the year when it was built or moved in.
The six-law school adopts the theory of binary eight-character luck and accompanying luck.
Due to theoretical differences, the rational style gradually divided into three schools, namely, Sanhe School, nine planets School and Kong Xuan Sanyuan School, after it spread to the Tang and Song Dynasties.
Famous Feng Shui masters in history are all proficient in the theories of Luan Tou and Qi management at the same time, and comprehensively apply them.
In addition, there is a school of Jianghu magic. The school uses unscientific magic to solve the unlucky position of Feng Shui, and changes folk beliefs such as layout and transportation.
