Is there a roof in front of your house that interferes with Feng Shui? That is, when I am at home, his door faces south, and the corner facing west is right in front of my house.

If the distance is very close, it is an arrow that shoots at the house. This is one of the forms. It should be properly solved.

If it is beyond 100 meters, it is not a form. If put in the right place, it can also be used as a writing style.
