The doors are not opposite, depending on whether there is a door facing the back of the exit door. If there is, we must try our best to resist it. Hang a gossip mirror at the company gate, enter the company gate, and place a screen opposite, so that you can't see a cactus in front of the screen. Stop counting. If there is no third door, just enter the company door, opposite. )

for reference only

In this case, the Eight Diagrams mirror hanging at the door of the company should have a tiger's head, a pot of cactus on both sides of the door, and an elephant of Chairman Mao hanging on the front wall of the company.
