If it is "Feng Shui" in the superstitious sense,
If we use modern scientific theory, it may be that the environment is polluted (such as radiation, magnetic field, etc ...), and the land is likely to have problems.
I have met many old people who died soon after moving to a new building because of the pollution of building decoration materials. There is radiation in many stones. There is a report on TV that the man died inexplicably because he bought a beautiful stone and threw it away. Many chemical raw materials have also been polluted.
