The database of Sun Yat-sen University Library is quite powerful, but it is only open to campus network users. Campus network refers to the local area network under the management of Sun Yat-sen University Network Center. Most of my classmates and I use the campus network.

In order to facilitate teachers living off campus to use campus resources, the network center of Sun Yat-sen University opened a VPN tunnel. Students and teachers can access campus resources through VPN tunnel ~
