Home feng shui taboo, ceiling taboo?

The ceiling on the living room roof is high above the sky. For residential feng shui, it is a symbol of the sky, so it is very important. The average height of modern residential buildings is about 2.8 meters. If the roof is decorated with fake smallpox, and the design is slightly improper, it will be quite tiring, and there will be a strong sense of oppression when the sky falls, and the residents will be under too much pressure.
