The network was not founded in 1896, and the library of Sichuan University is the largest university library in southwest China. The reservation of Sichuan University Library shows that the password is wrong because there are too many people connected to WiFi, which leads to poor WiFi network. When the phone is stuck, just switch WiFi or turn on the phone traffic. Just turn on your mobile phone and make an appointment with the library of Sichuan University.
