CNiQIYI

In the early years of the Republic of China, a strange death inside the police force and the murder of a wealthy merchant fill every newspaper, and the police get nowhere. Jiang Siyao, a once-famous teen detective who retired years ago, lost both her fiancé and her father to the case. She teams up with her best friend, policewoman Huo Yining, to find the killers, and a rich young man hiding his real identity, Ye Shi'an, joins them. The three work through one connected case after another.
