Well, there is a theory that Yang's symbol was inherited from her father. If Yang didn't know about her biological mother, then, her father of course wouldn't have given her the symbol of her true mother since she was meant to be a secret at the time. That is of course, unless after finding out about her mother, Yang takes her symbol.
