The old me is gone, and now I'm thinking about rain and snow.

This is a famous sentence in the Book of Songs, which, like a painting, expresses the feelings of a traveler who is away from home to the fullest.

It was spring when I went out, and the willows were dancing. When I came back, it was already rainy and snowy in winter. At this time of year, everything he has experienced is self-evident.

Recall that when I went out, Yangliuyiyi blew with the wind; On the way back now, the snow is flying all over the sky (sentimental).
