The house is moldy and the feng shui is not good.

The whole house is moldy for no reason, and I'm not sure if it has anything to do with Feng Shui. To find out why the whole house is moldy, you should observe whether the whole house is well ventilated and whether the water evaporates from the walls and underground. If it is not for this reason, it should be related to your house and ancestral graves. The whole house is moldy, just give you a warning that something is going to happen.
