What is "Feng Shui"? There are countless people who have defined Feng Shui from ancient times to the present. However, the first person to define Feng Shui in history was Guo Pu of the Jin Dynasty. He said in his famous book "The Book of Burial" : "The person who is buried takes advantage of the Qi. The Qi will be dispersed by the wind, and will stop by the boundary water. The ancients gathered it to keep it from dispersing, and moved it to stop it. Therefore, it is called Feng Shui. The method of Feng Shui is to get the water first and hide the wind second. It can be seen that the art of Feng Shui is also the art of phase and earth. The core is people's choice of living or burial environment and the processing of the changing laws of the universe, in order to achieve the purpose of seeking good fortune and avoiding evil. Feng Shui can be divided into Yang House and Yin House.
