Why don't people in China like to sleep with the mirror facing the bed, while foreigners don't mind? Because the bed I'm sleeping in now is facing a mirror (when the mirror opens, it's the wardrobe)

This is a different manifestation of cultural tradition, and it is also the reason for China's geomantic health preservation. If nothing else, just say the simplest point. If you wake up in the middle of the night and suddenly find a person standing by your bed, will you feel scared and will there be shadows in your heart in the future? In fact, this is yourself in the mirror, but it will scare you at night. This is the simplest reason why the bed can't look in the mirror.
