Why can't the mirror face the bed?

In ancient times, it was said that mirrors were used to ward off evil spirits, which affected health. Scientifically speaking, the mirror reflects light to the body, which will cause neurasthenia, poor sleep quality and other adverse reactions. People's sleep alternates between deep sleep and shallow sleep. During light sleep, people's conscious activities may appear, directly corresponding to the line of sight, causing external interference and being easily awakened.

From the perspective of geomantic omen, there are many taboos in the placement of mirrors. Especially the mirror facing the bed is very bad and must be avoided as much as possible. The statement that the mirror is facing the bed should start from the history of the mirror.

In ancient times, mirrors were used to ward off evil spirits. Li Shizhen, a great doctor in Ming Dynasty, said: An ancient mirror is like Gu Jian. If there is a god, it can ward off evil spirits. Anyone should hang a big mirror to ward off evil spirits. Mirrors are often hung on buildings, which are mainly used to reflect evil spirits, fight against oncoming evil spirits and avoid being destroyed by evil spirits. For example, the Forbidden City has a huge crystal mirror. In the place where Yongzheng studied and rested in Yangxinzhai, there is a wooden screen wall at the back door of the house with a mirror hanging on it. These are actually "Feng Shui mirrors".
