This maxim is taken from the ancient poem "Long Song Line" written by Han Yuefu. The original poem goes like this: The sunflower in the green garden, the morning dew waiting for the sun.
When the sun is shining, everything is shining.
Often afraid of the autumn festival, Kun, Huang and Hua's leaves will decline.
1. When will rivers return to the west when they reach the sea from the east? If the young do not work hard, the old will be sad.
2. It can be seen that the last two sentences are the conclusion of the whole poem and the main purpose of the poem.
3. The poem uses the image of the sunflower in the garden, flourishing in spring and declining in autumn, to describe the beauty of life in the youth and the misery of old age; As well as the analogy of the passage of time with the river flowing eastward and never returning, not staying for one person, are just for the last two words of warning.
