I know in Chinese people sometimes use other common words or phrases to tell people what characters their Chinese name has.
My Chinese name is Yuan Li Heng (袁禮恒)
For Li I can say Li Wu 禮物 and for Heng I can say Yong Heng 永恒. Yuan is a little harder because from I've heard, it's more just a common surname.
What's usually the best way to tell people what character it is in Chinese if the character itself doesn't really have any associated meanings?
