In addition, CUHK has no campus shopping network, but there is a flea market in BBS (bbs.sysu.edu.cn). At the same time, bbs is also one of the main tools for school communication, and it can also be accessed from the outside, but you can't speak without an account.

The study on campus is mainly the library. The library homepage can be accessed from the outside, but access to the database inside must be the IP of the school.
