1962, marshal Zhu De visited the Shilin, with an inscription: "The peak stands on the wall, and thousands of peaks overlap." Eight words, due to insufficient preparation, only eight pieces of rice paper, Mr. Zhu said modestly, don't leave your name, don't leave your signature and time. Think about how many people like to scribble their names "Come here" in some scenic spots. Today, we can still feel Mr. Zhu's open-minded virtue.
