LONG POST AHEAD.

Ok, so, if you want to watch a light-hearted series of solving crimes, and enjoy the atmosphere of The Republic of China in the mid-1920s, then this series is suitable for you. The cases were well-written and the deduction was logical. Lu Yao and Qiao Chusheng, two male characters in this series, also have a good chemistry. Qiao Chusheng provided Lu Yao a comfortable life by buying things and protecting Lu Yao, and Lu Yao solved the cases for him, improved his reputation. Their chemistry was a big plus. Beside that, the filming set and the clothes were beautiful and stylish.
Now, let's come to the minus side of this.
The female character, Bai Youning, a journalist, is very irritating. Yes, in the first few episodes, I could still empathize with her, and hope that she could have some developments. But she just didn't change. After 7-8 episodes, she still wrote tabloids about cases. She belittled Lu Yao, and even pretended that she was kidnapped, made Lu Yao and Qiao Chusheng worried to death and tried to save her. She was just too annoying, and her chemistry with Lu Yao was just unbearable. I could not understand how Lu Yao could love her, because all they did through nearly 32 episodes was bickering and fighting. But then, in episode 30, they kissed, episode 36, they got married and went to Paris, left Qiao Chusheng all alone in Shanghai after all. Poor Chusheng, he had done anything and everything to protect both Lu Yao and Bai Youning, but he was left alone in the end.
In conclusion, if you don't really mind about the ending, then this series is suitable for you. If you do, then please consider twice before watching it.
