What does mirror network language mean?

Mirrors are the most common things in people's homes. Everyone can't live without the mirror, because we usually comb our hair, wash our face and make up in front of the mirror and arrange our clothes.

Another meaning of mirror is. The standard to measure a person's good or bad, good or ugly, can also be called a mirror. The mirror here is not the mirror we look at every day. It is through this standard that a person's quality can be illuminated.
