For fans, the jersey is like a representative, or a flag. In basketball, we think of Yao Ming when we see the number 1 1, Kobe when we see the number 24, and Jordan when we see the number 23. It can also be said that the jersey is like a kind of sportsmanship. When we see these jerseys, we will think of these players. Sometimes we buy jerseys of these numbers to encourage ourselves.
