From the perspective of geomantic omen, what is a gnashing door?

In the residence in Figure 1, although the entrance door and bedroom door are not facing each other, the gap between the two red lines is still facing a part, just like sawtooth, which is a typical gnashing door. In addition, the window facing the door also belongs to gnashing feng shui.

Opposite the door means that two doors are opposite, while biting the door means that two doors are partially staggered, but not completely staggered, and some are opposite. Just like going to the door, gnashing doors can be avoided through decoration. If you can't avoid it, please open the five lines of gossip symbol on the online wealth network and cooperate with the Yin-Yang five-element amulet to resolve it.
