Your snail mail contains four sheets of paper: BLCU map, Application notice, JW 202 form and school guidelines. Most of you, who are going to China for the very firsttime, might not be familiar about the JW 202 form.
A JW 202 form is produced by the university you applied in once you have been accepted as their student. This contains your personal information as well as a seal from the Chinese government to prove that the form is official (and that you have actually been formally accepted). This cannot be taken from the internet faxed but only forms sent through snail mail shall be considered valid.

Your JW 202 form shall also be used in acquiring for a Chinese Visa. You should submit this form along with the other requirements for visa application when applying through the Chinese embassy.
I hope I helped :)
