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

2. 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, black hair does not know how to study hard early, and the white head regrets learning late.

Flowers will reopen one day, and life is no longer a teenager.

6, solar terms do not spare seedlings, time waits for no one.

7. Time will not come without two mornings in a day.

Time flies, the sun and the moon fly like a shuttle.

9. This is the night when people read.

10, the prime of life will never come again, and time and tide wait for no man.
