English Translation:
In the Song Dynasty, there was an archery master named Chen Yaozi. He could hit the target every time and was very proud. An old oil seller watched and only nodded slightly. The old man poured oil through the hole of a copper coin into a gourd without touching the coin at all. He said: "This is nothing special, it is just practice making perfect."
