The first thing depends on the patient's condition. Some diseases have nothing to do with feng shui.
Secondly, how old the patient is, Feng Shui can affect his age.
Older people, in modern terms, will certainly have an impact in their fifties and sixties.
Young people will also have an impact, but young people are full of yang and windy.
Water has little effect.
Again, it depends on the house, the light in the patient's house is good, and
Are there other people living in the family, and how many people live in what area?
The accumulated house, you know, is a haunted house, and the patient himself is sick.
Yang is no good. If you live in a mansion, you will lose your life.
Others can only be observed on the spot. There are many factors, which are impossible.
Say it all.
