Why do I have to go left and stand right when I take the elevator?

This is a habit of China people (just like going up and down stairs to the right, it is a habit and there is no reason). Some people can walk on the left in a hurry, those who are not in a hurry can stand on the right, leaving room for those in need on the left. This is an act that reflects the quality of the people. I hope everyone can do it.
