The "tree in front of the door" should be treated well and not ruined. Because trees can summon gods, they are also spiritual. If a tree grows in a bad place, we can choose to cut it off. For example, if leaves encroach on doors and windows, we can also melt them in our way. The method is simple. Using nine circles of red oil paintings on the tree can alleviate the rush of the tree. A folk geomantic omen is to entangle trees with chains, which can also reduce the lethality caused by trees.
