Most importantly, the world can't stay. What does Zhu Yan mean by this poem?

Meaning: The most unforgettable things in the world are the youth that never returns in the mirror and the fallen flowers on the tree.

It is the words of Wang Guowei, a modern poet, to read all the bitterness of saying goodbye to the end of the world from "Dead Hua Lian". The author compares flowers to his wife. By writing what he saw when he came home from the torment of parting, he expressed the complex feelings of shame, regret, love and pity in his heart, and expressed the author's sigh that time flies.

The original poem is:

After reading all the bitterness of leaving this world, there are still so many scattered flowers that do not return. There is nothing to say at the end of the flower, and the green window is spring.

I will tell you under the acacia lamp that I have new love and old hatred for Qian Qian. Most importantly, the world can't stay, and Zhu Yan's words are reflected in the mirror.

Translation:

I have experienced the pain of leaving this world, but when I came back, I saw such a scene of falling apart. She and I, at the bottom of the flower, looked at each other in a daze and said nothing. Fangchun under the green window is as late as the weather.

Originally, I was going to tell you about the lovesickness after parting in the midnight light. However, a little new pleasure evokes endless old hatred. What I can't stay in the world is the youth that never returns in the mirror and the fallen flowers on the tree.

Creative background:

In the 22nd year of Guangxu (1896), the poet married Mo and said goodbye to his wife two years later. He wandered in Shanghai, Japan, Nantong and Suzhou and spent ten years with Mohs. In the spring of the 31st year of Guangxu (1905), the long-lost poet returned to his hometown of Haining. Only then did he realize that his wife Mohis, whom he had not seen for a long time, looked haggard, which was quite different from what he remembered.

On the one hand, Mo's old age is related to the waste of time, on the other hand, it is also related to her infirmity and housework. Looking at his old wife, Wang Guowei, who is sensitive and affectionate, is very sad. This word may have been written at this time.
