When I was young and careless, I thought that something could do what people wanted. Fish swim in the flowing water, but people are not as good as fish. The world is ups and downs, what is easy to get is easy to lose, and what is rare may not be able to be held tightly in the hand. Sadly, it is destined to be enjoyed without life. What you see is not true. I don't want it to be just a beautiful dream. The world is just a floating life like a dream.
