The Oil Seller
Author: Ouyang Xiu
Mr. Chen Kangsu was good at shooting, unparalleled in the world, and he was proud of himself. I took a shot in my garden, and there was an oil seller standing there to relieve his burden. He would not go away for a long time. Seeing that his arrows hit eighty-nine times out of ten, he nodded slightly.
Kang Su asked: "You also know how to shoot? Isn't my shooting also good?" The old man said: "There is no one else, but I am familiar with it." Kang Su said angrily: "You dare to underestimate my shooting!" The old man said: "I will know it when I drink the oil." He took a gourd and placed it on the ground, covering it with money. In its mouth, Xu used a ladle to drink some oil and drain it, then put it through the money hole, but the money was not wet. Because he said: "I don't have him, but I am familiar with it." Kang Su smiled and dismissed him.
How is this different from Zhuang Sheng’s explanation of the cow-pulling wheel?
