In Feng Shui, the door faces the corner of the building, okay?

No, this is a typical flushing. Please ask a knowledgeable Feng Shui master for advice. They may have ways to resolve it. Don’t take it lightly. It's about 4 meters away, and it's even worse if it blocks light. If there is a big road between the corner and the door, the murderous intention will be reduced. If there is no way and the sun is blocked, it will be a hidden murder caused by the mud tip. If the angle is to the left, it will be disadvantageous for a man, and if the angle is to the right, it will be disadvantageous for a woman. She will be seriously injured, and her family's financial and spiritual life will be greatly damaged. You must have an expert resolve it for you. There are many small methods, so I won’t go into them
