Original text: Sunflowers in the green garden, the morning dew awaits the setting sun. In the spring of Budeze, all things will be radiant. I am often afraid that when the autumn festival comes, the yellow flowers and leaves will wither. Hundreds of rivers flow from 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 miserable.

Translation: The sunflowers in the garden are all lush and green, rising under the crystal dew in the sunshine. 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.

Kui: "Kui" as a vegetable name refers to one of the important vegetables in ancient China. Morning dew: early morning dew. Xi: Dawn, extended to the sun shining. Kunhuang: describes the appearance of withered and yellow vegetation. Baichuan: big river. Shao Zhuang: young and strong, referring to the teenage years. Boss: refers to old age. Disciple: In vain.

The whole poem uses scenery to express feelings, and is based on emotions. It embodies the life philosophy of "young people don't work hard, old people will be sad" in vivid images such as the morning dew is drying, the leaves are falling in autumn, and the rivers are flowing eastward. In the poem, with the help of the dew in the morning, the flowers and leaves falling in autumn, and the running water going east and never coming back, there is a sigh of the fleeting time and the short life, encouraging people to hold on to the life that flies by with time, and work hard to make a difference in their youth.

The emotional tone is positive. The main idea is reflected in the last two sentences, but the poet's thoughts are not simply stated. Instead, he extracts specific images full of beauty from the real world and teaches them through aesthetics.
