Switch the network to the school's own intranet first.

Log in to your school library with intranet.

Libraries generally have a "database".

Then, in the database, we found China HowNet, Wan Fang Data and other database websites.

Then, click in and you can download the literature you want.

Of course, if your school library doesn't buy it, there's nothing you can do.

After all, schools in every place are different.
