I hope an expert can give me some advice on bedroom feng shui issues.

The feng shui of a collective dormitory generally does not affect individuals. As the saying goes, "evil does not spread to the masses." You said that people often get sick in the dormitory. This has nothing to do with the feng shui of the dormitory. I think it may have something to do with the hygienic conditions of the dormitory. For example, the window in the dormitory is not often ventilated, the indoor space is confused, the dormitory is damp, the garbage is not removed in time, and there are microorganisms If it breeds, it doesn’t get exposed to the sun often, so there may be some kind of radiation in the room, etc. I suggest that you pay more attention to hygiene, bask in the sun frequently, open windows frequently, raise a few pots of flowers and plants that can protect against radiation and purify the air if possible, or buy an air purifier or something. In addition, don't stay indoors all the time, go outdoors and do aerobic exercise more often.
