1, can gather gas,
In fact, gas gathering mainly refers to the gate. Generally speaking, it is better not to have too many doors, but to be more specific, including the fewer back doors, which is beneficial to gas gathering.
2, can't let the gas be too miscellaneous.
Most people with too much gas will feel that there are fewer doors, but it is obvious to use doors to divide the gas in each room. The gas in each room is different (sometimes the smell can be distinguished). The clearer the division of labor, the more contradictions there will be, so many words will actually affect the atmosphere of the whole family, some of which are not harmonious and some are not suitable for cooperation.
In fact, the number of doors is not too particular. I mainly want to be practical. No more, no less, practicality is king.
