Why does the red light bulb stay on in the toilet? Any explanation? Thank you.

Toilets are heavy places in Yin Qi, and red light bulbs can increase the yang of toilets. Red light bulbs can be installed in big toilets in Yin Qi. If the toilet is in an evil position or a dead position and the light is relatively good, there is no need to install it, that is, install a red light bulb in the toilet to increase the yang of the toilet.
