Depeng's introduction: Fengxi, the number one scholar in the Ming Dynasty, admired the character and knowledge of Cai Lie, the master of Yundong Cave, and went to the mountain to visit him. The two of them climbed high, looked far, and gave advice on the country, and they had a close relationship. One day while walking and talking, I came to a rock and saw two huge rocks standing in front of me. They were shaped like the word "Peng". I was very happy and wrote the two characters "De Peng" in the title. It was a pun, so it became a paragraph. Beautiful scenery.
