It's a common grass from home. It's called "fish weed" in the city, and it's called "cracking root" in the home town, and it's a few more friendly and a few more relevant. And when the spring comes, all that is behind the house recovers, and in the mud of March there is a stream of water in the forest, with the crumbing of the crumbs, the crumbling roots of the ears come out of the ground as if they were springing out of the rain, and they dig out their heads, stretching out their purple umbrellas, and groaning in the wind. Fish weeds, many people don't get used to smell it weird, including me, when I was a kid, but every time I see a grown-up, I hear it's a lot of good for the body, I eat it。
