Why did Ruyan disappear from Detective Di Renjie III? Why was there no introduction at the end of the second film? What was she doing?

Di Ruyan didn't appear in Detective Di Renjie 3 because Qian Yanqiu had originally planned to ask Jiang Xinyan to continue playing the role of Ruyan when the third film started filming. However, Jiang Xinyan had changed careers to become a producer and couldn't participate in the film. Therefore, there were no actors like Yan in the third film. In the fourth movie, Qu Zha Zha took over the role of Ruyan. The director found an explanation for Ruyan's absence in the third film: Ruyan went home to take care of Di Renjie's brother, so she was not by Di Renjie's side in the third film.

Detective Di Renjie 2 was an ancient mystery drama. It was directed and scripted by Qian Yanqiu, with Liang Guanhua, Zhang Zijian, and Lu Zhong as the main actors. The play was composed of three confusing and thrilling stories: The Suspicious Shadow of the River Pass, The Snake Spirit, and The Bloody Jiangzhou. The story took place during the Zhou Dynasty. Di Renjie was appointed as the general manager of Hebei Province's army to investigate the reasons for the failure of the border war. The drama combined suspense, horror visual elements, and various emotional scenes, adding warmth to the thrilling case. The specific plot content included the adventure story of Di Renjie and Li Yuanfang, the teacher-student relationship between Di Renjie and Zeng Tai, as well as the encounter with Wu Zetian.

The reason why Li Yuanfang listened to Di Renjie so much was because he was Di Renjie's student and assistant. In Di Renjie's eyes, Li Yuanfang was a capable, talented, experienced and far-sighted detective. Therefore, Di Renjie trusted and relied on Li Yuanfang. In addition, in the plot, Li Yuanfang also realized that in addition to wisdom, detective work also needed to abide by the law, respect evidence, respect human rights and other basic moral principles. Therefore, he would always listen to Di Renjie's command and guidance to ensure the legitimacy and safety of his work.

In Di Renjie's second movie, Ruyan was originally a bad person. She was originally a member of the Snake Spirit Organization and was sent to Di Renjie's side to spy and steal information. However, as time passed, her heart was gradually moved by Di Renjie and Li Yuanfang's sincerity. She eventually turned over a new leaf and was recognized as Di Renjie's niece. She helped Di Renjie solve the case in the play and was appreciated by Wu Zetian. Therefore, it could be said that Ruyan in Di Renjie's second movie eventually became a good person.
