Generally speaking, sitting on a mountain is the best for water, but after detailed calculation (construction time and sitting direction), we can only know the influence after looking at the relationship between the flow direction of water and sitting on a flying star. For example, flying to the sitting side of the mountain star will damage the water, but sitting on the star will be prosperous. If you cooperate with the fleeting time, the change will be more complicated. In a word, Feng Shui is a comprehensive analysis, not a constant.
There is also a very serious saying that the pointed eaves of the opposite building, facing their main entrance, will also cause unexpected lotus flowers. The owner can hang Shanhai Town at the hedge to resolve it. In front of the home is a viaduct, railway or MRT track, and the car tide will flow day and night, causing strong wind speed and airflow to flood into the home.
