It is indeed related to "Feng Shui". "Feng" means the room is too stuffy and needs ventilation. If the "water" is not dry, it should be watered, and if it is watered, it should be watered thoroughly. If water accumulates for a long time, the roots will not be able to breathe. Also, the temperature, light, and nutrients must be appropriate. It’s okay to believe in Feng Shui, but I think it’s from a scientific perspective rather than pure superstition.
