Qi was a very abstract concept in ancient times. Qi exists everywhere, Qi constitutes all things, and Qi is constantly moving and changing. "Laozi" says: "All things carry yin and embrace yang, and the qi is in harmony." Zhang Zai of the Song Dynasty said in "Zhengmeng Taihe": "Taixu is invisible, the essence of qi, its gathering and dispersing, and the changing shape." ”
Qi is a very common and important concept in Feng Shui. There are vitality, death, Yang, Yin, earth, earth, Cheng, Gather, Na, Qi, Qi and so on. Qi is the source of all things. Qi changes endlessly and determines people's misfortunes and blessings. If a person wants to avoid the energy of death and take advantage of the energy of life, he or she must ask a Feng Shui master to "regulate the energy of energy". "Regulating qi" is very complicated. Only by combining yin and yang and five elements and obtaining "vigorous xiang" through field tests can we get "anger". With "anger" we can be rich. Therefore, Feng Shui is actually "the art of fortune".
