Can you hang a small round mirror in the middle of the gate?

It is not good to hang a small round mirror in the middle of the gate top. This is because the mirror will reflect the natural light received by the gate back, resulting in light and gas can not really enter the gate. Moreover, this practice often does not increase the feng shui of the house, and even destroys the original feng shui. Therefore, it is recommended not to hang a small round mirror in the middle of the door top.
