From the perspective of geomantic omen, can the medicine left over by others be eaten?

Don't take this thing Don't let others eat the rest of the medicine. Never talk about feng shui. One person is sick. It's too dangerous for you to take other people's medicine without knowing what's wrong with you. Feng shui is also unlucky. A person is a person's magnetic field. If you eat the leftovers of others, he will pass on his predecessor's magnetic field and his bad things to you. It is best not to use what others have used, but also to dry or disinfect it. Ji Ze!
