What's the implication of drawing lots for Susan?

Susan is almost a household name in China. The story of Yutangchun's encounter with her husband in trouble took place in Hongtong County, Shanxi Province. Until the ninth year of the Republic of China (A.D. 1920), the judicial bureau of Hongtong County still kept Su San's case file. From Susan's confession, the plot that Wang Jinglong is Susan's compatriot was discovered.

Su San, formerly known as Zhou Yujie, was born in Zhoujiazhuang, Datong, Shanxi in the Ming Dynasty. At the age of six, his parents died, and he was trafficked to a brothel and changed his surname to Su. She had two prostitutes before she went to the brothel, so she was named Saner. "Yutangchun" is her flower name. Wang Jinglong, the son of an official, met Susan on a trip and fell in love at first sight. Susan asked Wang Jinglong to work hard and vowed not to follow others. Leave Beijing and go back to Li. Although he failed to surpass Su San, he studied hard, went to Beijing for the second time and won the eighth place in the exam. On her way back to China, Susan was sold to Shen, a horse dealer in Hongdong, Shanxi, as a concubine. Shen has been away in business for a long time, and his wife Pi Shi is having an affair with her neighbor Zhao Ang. Susan, a forest area in Shen Yan, returned to Hong Tong. Li Shi was malicious, conspired with Zhao Ang to poison Shen, and framed him. In the first trial, officials in Hongtong County put Pi Shi and Su San in prison. Zhao Ang took out more than 1000 taels of silver from Pi's house to pay bribes. The magistrate of a county king took bribes and perverted the law, and extorted a confession by torture. Susan was punished, but he had to give in to the punishment and was sentenced to death. On death row, Pisces is at large. Just when Su San was sentenced to death in Hongdong, Wang Jinglong was promoted to Shaanxi on patrol. Wang Jinglong had heard that Susan had been sold to Hong Tong, but he didn't know how he really felt. Therefore, at the beginning of his tenure, he quickly visited Pingyang House and learned that Susan had committed a capital crime. He then made an unannounced visit to Hongtong County to learn about the unjust imprisonment of Susan, and immediately escorted all the people in Susan's case to Taiyuan. In order to avoid the suspicion of relatives, Wang Jinglong entrusted Liu Tuguan to try the case on his behalf. Liu was rehabilitated, Su Sanqi was rehabilitated, the real murderer was brought to justice, the corrupt king was dismissed for investigation, and he became a couple. Everything will be fine.
