Why are mirrors in the elevator often fitted?

A lot of us all know that in a normal elevator there is a mirror installed, what is the effect of this mirror? Many people can not answer, a few years ago, I could not answer.

1. Why did I look up at the elevator?
2. How to handle when the elevator falls freely

The reason why the mirror is installed in the elevator

I always thought that the mirror was meant to help those who entered the elevator to fix a little of their appearance. But when I happened to know the correct answer, I suddenly felt touched, like I was watching the light drizzle.

The answer is: When a disabled person in a wheelchair goes into the elevator, he or she does not need to try to turn around, but can still see the lights showing the floors from the mirror.

From small things or meticulous details that show respect for others, like a small chrysanthemum flower, though not beautiful to the "earthquake", but quietly quietly little by little fragrance, gentle but warm.
