Yes, tell me how the sewer is designed with good feng shui.

1. In the geomantic omen of Yangzhai, drains and sewers are the focus of geomantic investigation. Generally speaking, the inflow of water should be slow, not straight. The water flowing out should be curved and affectionate. If it is sewage, it should not stay for too long, but it is necessary to set up relevant columns at the exit, such as iron mesh, grit chamber and curved head. (Not to mention the role of geomantic omen, which plays a positive role in preventing mosquitoes, rats, cockroaches and other pests from entering the house and protecting the environment), it is not advisable to go straight, otherwise it is easy to commit mass annihilation, or the family will not gather wealth; 2. No matter whether it is an open ditch or an underground ditch, water can't flow out directly. The main reasons for crime are decline, bad fortune and increasingly poor family. It is best to design a circle from the back to the front. 3. Before and after the house, it should be good or bad when you see it clearly, and it should be chronic when you see it secretly. If you look after the rain, it will be slower and the degree of completion will not be high; 4. It is best for a house to have only one drain. For example, more than two drains represent a bad family relationship.
