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.
A man should study.
10, the prime of life is no longer coming, and time waits for no one.
Life between heaven and earth, if fleeting, is only sudden.
