I stumbled along the way, and I don't know whether I am stumbling or crawling. I have written so many things, but I actually don't know what I want to express. In an era when everyone is knitting scarves, perhaps few people like me are still writing in space. But today when I was sorting out old materials, I discovered A previous manuscript has no highlights, only memories, and even memories that I have almost forgotten. Putting aside the long-winded nonsense, these are the rest, just to leave traces. Under such a vast sky, I am just a small ant, hoping that one day I can shake an elephant, and keep working hard.
