How to express the school canteen with ancient poems, aphorisms and advertisements

Who knows that every grain of Chinese food is hard?

Ancient poetry edition:

There are thousands of students in the college.

What is a cold window for a few years?

Is there a gold house in the book?

I have a thousand millet here.

Motto edition:

The auditorium gives people spiritual food; The canteen gives people material food.

Advertising version:

We use food bags to interpret an era.

Eat with a big belly and broaden your horizons.
