Chinese Symbol for Sister,
mei4 or jie3

In Chinese, sister could refer to younger sister mei or elder sister jie.

The Chinese symbol for sister mei is made up of the radical for girl (left) and the word wei4 (on right) meaning "not yet".

Hence, mei is a girl who has not reached maturity.

The symbol for elder sister jie also has the girl radical but on the right it has a component which looks like a stool with two rungs standing on the ground.

Imagine the elder sister sitting on a stool in front of a make-up mirror and you get the idea of the difference between mei and jie
