Time is like running water, so we should cherish the poems of time.

1. An inch of time is worth an inch of gold, but an inch of gold can't buy an inch of time.

Don't eat all day and don't give up your job.

If young people don't work hard, old people will be sad.

4. I don't know if I learn early with black hair, but I regret learning late with white hair.

5. Three spring flowers are good, so learn early. Bloom has flowers, but life is easy to get old. -"precious time"
