Can the bedroom hang a mirror against the cemetery to ward off evil spirits?

The mirror is facing the bed: in ancient times, the mirror was 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 who hangs them should avoid evil spirits. The "God" here can be "Qi" or "Information".

The mirror is facing the bed: many ancient buildings are hung with mirrors, so there is a wooden shadow wall with a mirror hanging on it. These mirrors are used to reflect scenery with little influence, especially when they are used as "Feng Shui mirrors".

Mirror facing the bed: put the mirror in a detailed position indoors, not facing the bed and table in detail. If a mirror is facing the table and bed, the owner's anger will be reflected, which will affect his health.
