It means that spring is no longer allowed to look back, and it also means that with the passage of time, the years are in a hurry, spring has been advancing, and spring has been getting farther and farther away from people.
It also shows that we should not be allowed to look back on the past. With the passage of time, people must learn to face the reality and understand the mentality left by spring.
Spring is not allowed, the source of turning back:
Spring is not allowed, and then come back from "Xijiang Moon Farewell".
Drink the east wind and embrace the bright moon, but spring won't allow it, and then turn back. I want to buy osmanthus with wine, but I don't like it. There is another village, and the autumn wind turns. Don't stay. Raise a glass to eliminate sorrow through the ages, recite poems, dance and swim.
Meaning: Expressed the poet's lofty sentiments. Through the beautiful spring scenery, I drank poems and expressed my feelings for nine days.
A Farewell to Xijiang Moon is a poem written by Su Shi, a writer in the Northern Song Dynasty. The whole word is plain and appropriate, expressing his complex mentality of being powerless in his official career.
