Once upon a time, there was a teenager whose family was very poor. He lives by logging and reads by moonlight at night. There is a rich man in the village next to the teenager, wearing silks and satins, eating meat and showing off his wealth in front of others all day. One day, the rich man went out hunting, and the left and right attendants presided over the bow and sword for him. The eagle and the dog followed him, and they met the teenager on the road. The rich man insulted the teenager in public and said, "You are as poor as my eagle and dog." Teenagers don't respond to rich people. The rich man added, "Follow me and catch foxes and rabbits with my eagle and dog. Whoever catches me first will be rewarded. "
