The gate faces a hollow statue, ok?

The door is facing an empty image, okay? When the compass is combined with the actual terrain, there is an important principle that the reality is not empty. Your door faces the valley. If the front terrain, that is, the site of the hollow section is equal to the house site, that is, the terrain at the hollow section does not obviously pit downward, it is regarded as normal operation cooperation. If the terrain of the hollowed-out area obviously falls down and becomes a pit, it is not in line with the rules and is empty.
