What's your name? How do your parents call you at home?
In ancient(古代的) China, people have three names: the family name, the given name, and the courtesy name(字).
Do you know the famous poet Li Bai? His family name is Li, his given name is Bai, and his courtesy name is Taibai.
People use their given names when they are with their family or friends. And your elders(长辈)like your grandparents and parents call your given name at home. But in the workplace, people use their courtesy names.
Men get their courtesy names when they are 20 years old. Women usually get their courtesy names when they are 15 years old.
