Building a house on a big pit for ten years has sunk more than ten centimeters. Didn't room three commit geomantic omen?

It's not that you can't build a house in a big pit. Don't you have to dig a big pit and lay a good foundation before you can see what building to build?

This is normal. Your problem has nothing to do with Feng Shui, but your foundation is not good.

Be careful when living in such a house, because the foundation is unstable and the situation is not good.
