If young people don't work hard, the boss will be sad;

Flowers will reopen one day, and people are no longer young;

Learning is like sailing against the current, if you don't advance, you will retreat;

There is a road in Shushan, but there is no limit to learning the sea.

It is better to believe in books than to have no books;

Night lights and chickens are the time for men to study;

I don't know how to study hard early, but I regret learning late.

Mechanics is like ploughing, diligent and self-aware;

But if you do too many books, you will get old.
