In 1998, the agricultural machinery factory in a small southern town was not performing well. Chen Yan was divorced by his girlfriend and was still in debt. No one knew that in his dreams he always saw an old man wearing a green cloth gown, who taught him how to recognize metals, listen to sounds, and identify old objects. The family tradition of vomiting also taught him to control his hands and eyes. Others thought he was just an apprentice repairing machine tools, but he repaired imported milling machines and old copper furnaces found in ghost markets, and relied on his craftsmanship and vision to turn things around. When his ex-girlfriend's family came back, Chen Yan only said: I don't work overtime and I don't owe anyone.
