Nickname 绰号Nickname is very popular and it presents the good relationship between people.
For example, in my family, my parents give me a nickname and they call me with it all the time.
But someone calls my full name, who are not so close to me.
So when I hear my nickname, I know they are my friends or my families.
绰号是很普遍的，它代表了人与人之间良好的关系。
比如：在我家，我父母给我起了个绰号，之后他们一直是喊我的绰号。
但也有人叫我的全名，这些人的关系跟我就没那么亲密。
所以当我听到我的绰号时，我就知道喊我的是我的朋友或家人。
