1. "名門懸案:總裁夫人忙辦案" (Mingmen Mystery: The President's Wife Solves Cases): This novel follows a female Ph.D. student in medicine named Su Zilun who becomes a suspect in a crime. To clear her name, she transforms into a female detective and uncovers unexpected truths. The main characters are intelligent and the story is both sweet and clean.
