Why did Ju Sun hand Geng Min's notebook to Yan Ge in "The Eleventh Floor"?

The overall score of the missing eleventh floor is 2023 /

Director Sun hoped that Yan Ge could help Qu Jianghe, so he handed Geng Min's notebook to her. Because of Qu Jianghe's complaint, was investigated by the procuratorate because of the account made six years ago. For the sake of excellence, Yan Ge went to Liu Yutang, the deputy mayor, and she tried to protect excellence at all costs. Bureau Sun knew that Qu Jianghe reported Excellence to protect him from Meng Chuansheng's case, so he didn't want Yan Ge to save Excellence.

Sun Ju consulted Secretary Hao and confirmed that Yan Ge was a trustworthy person, so he told her about Geng Min and explained Qu Jianghe's self-defeating. Yan Ge is now the director of the Jinchuan City Public Security Bureau. She has a strong background in the public security, prosecution and legal system. Behind her is the organization. Now the Meng Chuansheng Group is too powerful, and it is far from enough for Qu Jianghe and the others to fight alone. Director Sun needs Yan Ge's support now, so he told her the whole story. Yan Ge is a principled person with strong judgment. With her joining, Qu Jianghe and the others will make their investigation much easier.
