The first time he came here, he was not familiar with the road here, and he came here after looking for a while by himself, and he was so scared that he cried.

1. Original text:

Yi Qiu, the good player of the whole country. Make the game of autumn and teach the two of them. One of them is attentive, but Yi Qiu listens; Although one person heard it, he thought that a great bird was coming, and he thought of the bow and shot it.

2. Translation: Yi Qiu is the best chess master in the country. He once taught two apprentices how to play chess. One of the apprentices was attentive, and he would do whatever Yi Qiu taught; The other man (who seemed to be listening to the lecture) was always thinking about how to draw his bow and shoot it down if a swan was about to fly over.

Although the two studied with Yi Qiu together, he was far inferior to others. Is it because he's not as smart as others? Of course not!
