Some people say that when buying a house, why not buy a house with a roof in front of it? Is there such a saying?

This question depends on whether there are sharp corners on the roof or eaves of the building in front, dragons or beasts, or anything particularly prominent, facing your house. If such a thing is aimed at you, it is evil. Try to avoid it. It doesn't matter if it's not pointed at. If you have already bought it, this situation generally needs to be solved. If there are some sharp corners in front of you, this place needs to be well designed to melt. Because this thing is also a magnetic field, it will affect the living environment and health of individual users all year round.
