What is Wang Zhi's "bad market"?

The Story of a Different Story was written by a man named Michelle, who lives in Shishi Mountain, Xin 'an County. During the Jin Dynasty, Wang Zhi cut down trees. When he saw the boy playing chess, he sang because he listened. Boys long for one thing and one quality, such as jujube stones. After a while, the boy said, "Why not go?" In terms of quality, the axe is rotten. When you come back, nobody will come back. (Biography of Southern Dynasties) Xin 'an County is in Quzhou, Zhejiang Province today. Shishi Mountain mentioned in the story has always been called Rotten Mountain because of this beautiful fairy tale. The story tells that when the king of the Jin Dynasty was chopping wood, he went to this mountain and saw several boys, some playing chess and some singing, so the king approached to listen. The boy gave the king something in the shape of a jujube pit. He didn't feel hungry after swallowing it. After a while, the young man said to him, "Why don't you go?" The king stood up. When he looked at his axe, the wooden handle was completely rotten. When he returns to this world, his contemporaries will cease to exist.
