Say the finishing touch.

The finishing touch of "A Note to Friends in the North on a Rainy Night" is: when * * * is cutting candles at the west window, it's raining at night.

Interpretation: If one day, we will sit together at home under the west window, cut candles and flowers, and talk to each other about our thoughts in the rainy night tonight, how wonderful it would be!

There is a poem that simply explains the reason for this feeling: getting drunk makes it difficult for you to sleep, and gambling books makes you pour tea. At that time, only Tao was ordinary. What really makes people feel close is those things that usually look unremarkable. The scene imagined by the author sounds simple, but it is not available, which can arouse the readers' interest.
