After the death of my father-in-law, what feng shui is related to my wife's frequent illness?

Your wife often falls ill after her father-in-law's death, which has nothing to do with geomantic omen, but because your father is eager to miss his dead father, resulting in a decline in physical immunity. The dead are gone. The living should take good care of themselves, which is a comfort to the dead. You should persuade your wife not to think too much and exercise properly to get better. Have a nice day.
