My mother-in-law and I both got gynecological diseases at the age of 50. Does this have anything to do with feng shui at home?

It doesn't matter, when women reach this age, they usually stop menstruating, their organs atrophy, their functions decline, their secretions decrease and their antibacterial ability deteriorates. It is easy to get all kinds of gynecological diseases, which has nothing to do with Feng Shui. That is superstition. If you are sick, you should go to the hospital and listen to the doctor's correct guidance. Don't take drugs at home.
