It means that young people should cherish life and time, be good at using every minute to constantly improve themselves, exercise themselves and achieve success, and don't wait until they are old and weak to regret their youth and waste their time. By then, it will be too late to feel pessimistic and disappointed!

The original intention of Red River written by Yue Fei is: My hero, we should seize the time to make contributions to our country, and don't waste our youth, because it will make us sad when we get old. Now it can mean that young people don't waste time easily, but just kill time casually until their temples turn gray and suddenly wake up, and then only sigh and sadness remain.

There is a famous saying about time:

1, where can I buy youth on Maijue Road?

2, the season waits for no one, and the moment is worth a thousand dollars.

3, flowers bloom on time, reading young.

4, the solar terms do not spare seedlings, and the years do not spare people.

5, there are no two mornings in a day, and the time is not coming.

6, time is like running water, and time waits for no one.

7. Cherish time and don't trust fate.

8. Lazy cows have more urine, and lazy people have more urine tomorrow.

9. Grasping one today is better than two tomorrows.

10, life cannot be wasted, and youth cannot be wasted.

1 1, wealth is like a cloud, and time is like a foot.

12, life time is fleeting, and the completion date is set early.

13, you can't see the beauty of flowers and trees without caring for petals.

14, if you don't cherish time, you won't get the value of life.

15, people who wait for time are people who waste time.
