How to send letters to college students? Is the address written in her class or dormitory or something? Is it written in xxxx class xx?

It should be written clearly that the department (college) of * * school has accepted * * class! There is no mailbox in the dormitory. At most, it is sent to the administrator. Maybe it will be lost. It is best to use the class mailbox, and the life Committee will take the letter and send it to the students who receive it in the class.
