Three evil spirits are a term commonly used in Feng Shui. It originates from the principles of the three combinations and the conflict of the five elements. The three evil spirits are composed of calamity evil, calamity evil and year old evil. The three-sha position is the direction that conflicts with the annual three-in-one five-element bureau.
Yinwuxu combines the fire situation, the fire is strong in the south, and the north (Hai Zichou) is its conflict, which is the three evil spirits (Hai is the calamity evil, Zi is the calamity evil, and Chou is the Sui evil, also known as the tomb evil). In Shen Zichen's combined water bureau, the water is strong in the north and rushes to the south (siwuwei), which is the three evil spirits (si is calamity evil, noon is calamity evil, and weiwu is sui evil).
Haimao is not in the wood position, and the wood is strong in the east, and the west (Shen Youxu) is the conflict, which is the three evil spirits (Shen is the calamity evil, You is the disaster evil, and Xu is the new year evil). In the alloy bureau of Siyou and Chou, the metal is strong in the west, and the east (Yinmao Chen) is the conflict, which is the three evil spirits (Yin is the calamity evil, Mao is the calamity evil, and Chen is the new year evil). Expressed in formulas, "Yinwuxu kills the north, Shen Zichen kills the south, Haimao does not kill the west, Siyou Chou kills the east."
