Which golf course in Changsha needs students to caddy?

None of them. Being a caddy is not that simple.

Golf caddies don't have to check the ball like caddies on a football field. Golf caddies need golf knowledge more than players. They will give their guests different hitting suggestions at different times according to the situation of the stadium. For beginners, caddies can even be their coaches. Better caddies need to know at least a little foreign languages, such as English, Japanese and Korean, which these students can't do.
