In this world, there is a disease that can only be infected but not contagious, and has no pathogenic bacteria. When people occupy a dominant position, they often underestimate the retreat, or even cut it off. When I look back one day, I find that all my advantages have been lost, and I start to regret it and try to bury it all in the soil and keep it dusty. But I found that the deeper it is buried, the faster it can be dug out. I call this disease - not knowing how to cherish.
