The slogan of Xiamen University Library became popular.

Slogan one: lovers! Stop distributing hormones in the library!

Obviously, this slogan is to tell students that the library is a place to study, not a romantic place. Starting from me, keep the library quiet.

Slogan 2: Shake your legs, maybe you have a motor?

This slogan is to remind students to pay attention to personal cultivation and not to shake their legs when reading. Although shaking your legs doesn't affect others. But it looks really indecent and affects your image in other people's minds.

Slogan 3: An apple is crisp and loud, and many mice are running here.

This slogan is to remind students not to litter and keep the library clean.

There are many similar slogans, such as:

Please handle the chair gently when driving back to the palace;

The book on the shelf says that this student is the noisiest student I have ever taken;

You chat, I chat, see you in the makeup classroom next year;

It's brave to face the shaking mobile phone on the table;

You talk, I talk, and everyone has to hang up at the end of the term.
