Guo Pu of Jin Dynasty in China was the first person to define Feng Shui. He said in the Book of Burial: "Buried people take advantage of anger. Qi is dispersed by the wind, and the boundary water stops; Therefore, it is called feng shui, because gathering makes it last, and action makes it stop. " In other words, when we choose a cemetery to build a house, we should find a "angry" place. "Qi" blows away when it meets the wind, and stays when it meets the water, which is beneficial to people's survival and development. Feng shui takes the land where water is obtained as the first class, and the land where wind is hidden as the second class. Geomantic omen is the knowledge and technology to study the polymerization and movement of gas in buildings. From 65438 to 0978, two American scientists discovered that "Qi" is "cosmic wave".
