In fact, this problem also bothers me! But give you some advice! If it's grade three, you can't get away! Only according to the arrangement of the school!

It should work! (We used to do this) Well, if you are a senior three, congratulations, you can't run away, even if you sue the Party Central Committee, it's useless! Let's get started. Choose me!
