How to hang up the line for the Feng Shui master who buried his ancestral grave?

In fact, this place also has different views, so I'll talk about our views here. First of all, we can't see a place blocked by mountains, because it is called aspiring future. Blocked, the future of future generations will be blocked. There should be a flat land in front of the grave, and the grave should be in the mountain ridge, not too steep. The left and right sides of the grave are called long rooms, that is, the eldest son should be blocked by the mountain on the left and the youngest son on the right, otherwise the businessmen will be unhappy.
