Use your account (student number) to open more windows. This is how we got here!

Or help each other with classmates, and each classmate hangs his own and others' (in some schools, a computer can't open multiple accounts, but it can open multiple different accounts)

It is not a problem to hang 10 to 20 hours a day, 30 to 40 can be used.

However, it is recommended not to be too crazy. For example, if you hang up for 30 hours a day, it's a bit unreasonable!

Teachers generally don't check carefully. Good luck! ! Hang up and remember to refresh!
