Does inlaying mirrors on the living room ceiling violate Feng Shui?

The color of the ceiling should be light rather than heavy: in ancient times, the heaven and earth were just chaos when they first opened, and then divided into two qi. The clear qi rose up and became the sky, while the turbid qi sank and became the earth. That’s why there is a distinction between heaven and earth. The ceiling of the living room symbolizes "sky", and the color is of course mainly light; for example, light blue symbolizes the bright blue sky; while white symbolizes the white clouds. The color of the ceiling should be light, while the color of the floor should be dark, in order to comply with the meaning of clear sky and heavy earth. If you install a gray mirror on the ceiling of your living room, it will give people the feeling that the world is upside down. Do not install mirrors on the ceiling. This is a Feng Shui taboo.
