2. Introduction to the original text
When the author was a child, he had to go through a ferry, and the ferryman was an old mute old man. Year after year, people get used to the old man's ferry, and they don't think of the dumb old man until one day the old man is ill and leaves, and the person who takes the ferry later is sloppy and unstable. The old man died of liver cancer, and finally people knew that he was a squad leader of the Red Army. Because he intercepted the devil and blew up the bridge on the river, the old man spent his life helping people ferry. The old man continued to donate to the local area to build a bridge before his death.
