If the school network is unstable or has other problems, you can download an APP called "Global Academic Express". Its icon is CNKI with white characters on a blue background, and it is the official APP of HowNet (I am not an advertising dog ~).

Key points: In addition to IP login, this APP also has the function of logging in according to geographical location. As long as you are near the school, you can log in in the name of the school!

I'm tired of typing so many words, please praise me ~ ~ ~
