Is the house on the slope feng shui good?

The house on the slope has bad feng shui. From a practical point of view, the foundation of the slope is not easy to hit. In addition, do you think the slope is more like a grave, which means that it is a place where feng shui circulates? If you build a house on it, Feng Shui will be blocked. Be sure to fill in a certain range of flat land around the house. Then build a house on the flat ground.
