1. A young man who does not know how to study hard will regret studying when he is old.

Extended information:

The motto "If a young man does not work hard, the old man will be sad" is taken from the ancient Han Yuefu poem "Yuefu Poems·Long Song Xing". The original poem is as follows: "The sunflowers in the green garden are waiting for the morning dew. The sun is shining in spring, and all things are shining. I am always afraid that the autumn festival is coming, and the yellow flowers and leaves will wither. When hundreds of rivers reach the east to the sea, when will they return to the west? If a young man does not work hard, an old man will be sad."

Interpretation: The sunflowers in the garden are all lush and green, rising under the crystal dew in the sun. Spring spreads hope all over the earth, and everything appears prosperous. I am often afraid that the chilling autumn will come, and the leaves will turn yellow and the grass will wither. Hundreds of rivers are rushing eastward to the sea. When can they return to the west again? If a young person does not work hard in time, he will only regret his life when he grows old.

Appreciation: As long as there is sunshine, rain and dew, all things in nature will be able to bear fruit in autumn, but people are different; they cannot succeed without their own efforts. All things decay in the autumn, but they have realized the value of life, so they are not sad. This is not the case for people. Because they are "young and don't work hard" and become old and achieve nothing, it is equivalent to walking through the world in vain. It is undoubtedly better to mobilize readers to think than to think for them. Precisely because of this, this poem avoids the boring life preaching, and makes the final aphorism appear powerful, deep and implicit, like the long tolling of a bell, deeply touching the hearts of readers. The word "tu" at the end of the sentence has a profound meaning: first, it means that the boss has no success, and life is wasted; second, it means that when you wake up in old age, you will not be able to help, and you can only sigh, which is intended to emphasize that you must work hard in time.
