First, the original:

Qiu Yi is the best athlete in this country. Let Qiu Yi teach two people to play chess. One of them was absorbed in it, but just listened; Although one person thought it was a swan, he tried to shoot it with his bow. Although I learned chess from the previous one, chess is still not as good as the previous one. Why do you know it? That's not true. (selected from "Mencius Gaozi")

Second, translation:

Qiu Yi is the best chess master in China. He once taught two disciples to learn to play chess. A disciple was absorbed in what Qiu Yi taught him. The other person (although he seems to be listening to the lecture) is always thinking about how to open his bow and arrow and shoot it down. Although they study with Qiu Yi, he lags far behind others. Is it because he is not as clever as others? Of course not!

Third, comments: you must be quiet before studying. If you don't learn, you can't learn widely, and if you don't stay still, you can't succeed.
