Lin Bu lived in seclusion in a lonely mountain in Hangzhou. He often raised two cranes, but he flew vertically into the sky, circled for a long time and re-entered the cage. He often visits the temples in the West Lake by boat. When guests come to stay, boys go out and sit at the door to lengthen the guest's seat so as to open the cage and lift the crane. You will return to the boat after a long time, and Gai often takes the crane flying as a test. I am arrogant and have learned a lot, but I can't play chess. It is often said that there is nothing in the world, but I can't stand playing chess.
