Only when the "Ming Gua" is the main one, can you choose a house and a room based on the "Ming Gua". If the "Zhai Gua" is the main one, how do you choose a person for the house?
"East Fourth Life" chooses "East Fourth House" to live, and "West Fourth Life" chooses "West Fourth House" to live. If "East Fourth Life" buys "West Fourth House", then choose to live in "East Fourth Room". But what if there is only "West Fourth Room"? The bed must be arranged in the "Xiangsheng" position.
