Yang Zhai Feng Shui: In the application of Feng Shui in China, if the room you live in is huge (the room of the master is necessarily the largest, and the room of the wife is smaller than that of the master), otherwise the wife will suppress the momentum of the master, hinder her husband's fortune, and the family will not be stable, which is the so-called "wife taking the husband's power", and the wife will easily not have children. Maybe this is not an absolute truth, but it is correct to some extent. Therefore, in ancient times, three wives and four concubines, the husband's life and the concubine's horoscope were matched, and the position of the master bedroom was usually in the middle, and its position was biased towards the big room (wife, mainly the east wing, the east wing) or the small room (where the concubine lived, she had to live in a smaller room in the west wing), so there was China's ancient "The West Wing".
Yin House Feng Shui: This is also one of the methods of housing allocation in Feng Shui, but because it is the tomb of the deceased, it is necessary to set the direction of the tomb owner, mainly with Zuo Qinglong (East) as the big room; The former Suzaku (south) and the latter Xuanwu (north) are the second rooms; The right white tiger (in the west) is a small house, so it is a geomantic pattern of the yin house, depending on whether the grave owner is good or bad for the big house or the small house after his own burial, or whether such a position is a shade for the descendants of the grave owner.
