Li Shangyin's "Notes to Friends in the North on a Rainy Night", you ask about the return date, and the rain rises in the autumn pool at night. When * * * cut the candle at the west window, but talk about the rain at night. This poem is about a wife's infinite yearning for her husband. She is looking forward to the return of her relatives, but she can't see each other for a long time because of the long journey. Lonely, lovesick and helpless, I finally couldn't help but borrow Hongyan's book and ask, when will I come back? In order to survive, distant relatives can't help themselves and don't know when they will have time to get away. Moreover, it's a long way to go in Xiu Yuan, and perhaps when the rain is full of autumn pools, the beloved people will have a chance to meet each other. In this lovesick day, she always dreams that the late rain will come earlier, so that the husband and wife can talk all night under the west window. They gently cut the sintered candle thread with scissors, telling each other the sadness of parting and expelling the pain of acacia. "* * * Cut the candle at the west window" is the pursuit of life and the yearning for a better and happier life.
