I have never read a famous book, personally. The origin of human beings developed from rivers to tribes and gradually evolved into today's human beings. The second wish is that human civilization has also developed from rivers, lakes and seas. The third literal understanding is that history is like a river, which has been rushing, or turning the tide, or calm. But it won't flow back. No matter what happens, it will move on. This is also history! . Personally, I think so. I hope it helps you!
