The center line of feng shui

If the center line of the south of the house is between 157.5- 172.5 degrees, open the west door; If the center line is between 172.5-202.5 degrees, open the front door; You can't open the east door.

But it's wrong to open the door in front, because the tree is too close. If you can move the tree forward 10 meter and open the south gate, it belongs to Wang Cai Wang Ding's house.
