There is water in the south of the house, which is really good for the whole house.
But in the north, if the room is empty, women with kidney deficiency will have tinnitus and high blood pressure.
It is suggested to put higher things or furniture in the north.
It's best to leave the goods in the south empty, as long as they are lower than those in the north.
Improve the position of Qinglong in the east and lower the position of Baihu in the west.
This is basically enough.
I hope I can help you. Good luck.
