Please recommend a Chinese mystery novel.

I'm looking for the name of a Chinese mystery novel! He remembered the general content of one of the volumes of the novel: The naked body of an old woman was found on a swing in the park. The old woman's hair was braided. Something had been stuffed into his private part (I couldn't remember it clearly with crayons). The murderer seemed to be the grown son of the female victim in an old case. The female victim was also placed on the swing in her yard when she died. His son seemed to have become a police officer. The murderer who killed the female victim was thought to be her colleague and admirer, and was finally executed. But it was someone else. The male colleague was wronged. The male colleague seemed to have given the female victim's son a crayon set. The male colleague's son seemed to be friends with the female victim's son. As for whether the son of the female victim or the son of the male colleague would become a police officer, he had already forgotten. This was probably the plot of this volume. Please name this novel! Thank you! Thank you!

I recommend Detective Chang 'an Street. This light-hearted detective novel tells the story of a street police officer who traveled to the prosperous Tang Dynasty and became a national detective. I hope you like my recommendation.
