When cloth merchant Zhao Dexin passed through the ancient tomb, he met the scholar Qin Qiufan and the girl Hua Hongyu in the underworld. Qiufan was killed by robbers on the way to Beijing, and his body was thrown into Hongyu's cemetery. Wang Jinqing, the nephew of Hongyu's stepmother, once forced Hongyu to marry him. Hongyu could not bear the coercion and hanged herself. Later, Wang Jinqing was killed for taking someone else's wife, and he still did not let Hongyu go in the underworld. Qiufan and Hongyu loved each other, but they could not get married in the underworld because there was no evidence of their marriage in the world.
