Within ten steps, the grass is growing; Within a hundred paces, there is no garbage.

First-class university, the sky is high and the clouds are light, and there is no garbage.

It's dusty on campus. How about running with the bulls?

Love life and health.

Getting rid of stubborn dirt is collecting fun.

Disposable plastic bags, are you still using them?

For life, defend life

Habit is cultivated for a lifetime, and hygiene is emphasized for a lifetime.

Teachers live, teachers and students live.
