The gate faces east, the factory building is U-shaped, and the other three sides are other people's fish ponds.

The gate faces east and should be on the southeast side, commonly known as the southeast gate, which is the Yang gate. U-shaped factory buildings, commonly known as "missing edges and corners", are not allowed in houses where people live, but it doesn't matter in factories. Because of the strong wind in the northwest and southwest, we need a variety of trees to shelter from the wind and rain. The other three sides are other people's fish ponds, and the water is rich, which is a good thing by rights. Feng shui theory is about the influence of wind and rain, which can only be seen on the spot and involves a lot.
