This kind of land is built on geomantic omen. How should it be built? We need to pay attention to which doors should be opened on the grass over there. (Explain or correct what I just said) I mean

Your land looks good. You can open the door from two directions. When building a house, you'd better sit west to east. The sun rises in the east, and in the morning and evening, there will be better sunshine in the hall to supplement the yang and dispel the moisture in the house (generally, Feng Shui thinks that moisture is a place where ghosts and gods like to gather). You can also open a door at the intersection in the north. This door should not be bigger than the other one. Just remember the toilet when you build the house.
