The recipient directly fills in: xx Section of Changzhi Education Bureau, and the documents will be received at that time. Express delivery may not be able to send it in. I'll make an internal call. The department will naturally receive it As for whether they will call you back, it is not easy to predict now. When you think the express mail is coming, you'd better call the department yourself, which is also a courtesy.
