The case of Cao Dong in the Hunting Crime Illustrated Book is the prototype of Lao Rongzhi. Relatives of Chu Yingzi's victim revealed in the play that the victim was a man and the suspect was a couple. The man had been running away after the woman was arrested, and as a result, he could not be sentenced temporarily.

Shen Yi saw Chu Yingzi. After the meeting, many plots were cut away. Only the defendant recalled the wedding photos, which alluded to the relationship between marriage life and the case, the idea of ??the case and the victim. His true identity was almost never revealed, and it ended hastily.

In "The Illustrated Book of Hunting Crimes", Cao Dong has complicated feelings towards Chu Yingzi. On the one hand, he fears that she will deceive him, so he inquires about the situation from the painter Shen. After seeing the portrait, he becomes furious. On the surface, Chu Yingzi sees through life and death. , in fact, in order to survive, the storyline was greatly cut.

Chu Yingzi must have confessed to the man for more rights, such as a reduced sentence. She has always claimed that she was forced by the man, and the other party was the first offender. She was just a poor person, and she was not the same as Lao Rongzhi The posture is exactly the same.
