In Journey to the West, Emperor Taizong Li Shimin of the Tang Dynasty did not stop Wei Zheng from killing the Dragon King, so the ghost of the Dragon King after his death often harassed Li Shimin and made him sleep poorly. In order to solve this problem, Li Shimin asked Qin Qiong and Cheng Yaojin to guard the door for him. The Dragon King saw the two generals at the gate of the palace and could not get close to the emperor. So the Dragon King asked the King of Hell to let him confront Taizong of the Tang Dynasty. As a result, Taizong of the Tang Dynasty died. Before going to the underworld, Wei Zheng gave him a letter saying that in the underworld I have an old acquaintance of mine, Cui Yu, as the judge. You will be fine if you go and find him. As a result, Emperor Taizong of the Tang Dynasty went to the underworld and saw Cui Yu. When Cui Yu checked the book of life and death, he found that his life span had expired, so he gave him a lot of money. After thirty years, Tang Taizong came back to life.
