Yang Zhai's geomantic omen is high before geomantic omen and low after geomantic omen.

It is a taboo for feng shui to sit on the low side of the mountain and sit on the high side as opposed to feng shui. You have also read some books about this estimate. But according to what you described, there are tall buildings behind the mountain. This is the highest in the feng shui environment, and all the big layouts can help. However, after all, it is difficult to collect water because of sitting high. You can leave the door open for a long time or put a sucking elephant indoors to relieve it. Sitting on the mountain, you can put a cement board at the back.
