Both are directed by the same talented director (xin shuang); they are both modern crime thrillers that explore different social themes ie family dynamics, human behaviour, 'good' people making bad decisions, the impacts of those decisions etc. Both are superb productions that should be watched by more people!
Both dramas are set in Shanghai and revolve around the lives of 30+ aged women (Ode to Joy has some 20 somethings) as they navigate the big city struggles, career, relationships, family, friendship, and more.
