Originally I was going to drop "The Knockout" after watching about 4 episodes. I found it boring, but I am glad I stuck with it as the story unfolded.

It showed that An Xi was a good and high-standard moral policeman, who had to walk away from being an investigation cop because of corruption, and too many of his friends were killed and hurt. Eventually, he was transferred to the right team from Linjiang province to help and work with him to eliminate the corruption of Jinghai and its high-ranking major and police officers.

Li Yi Tong did not have much screen time in this drama, but I think it was the best acting job that I have seen from her.

Zhang Song Wen, in my opinion, should win the golden eagle award for his role as Gao Qi Qiang. His acting is superb and carries this drama beautifully, and the entire ensemble is excellent. Everyone from minor to major supporting roles.

As it was revealed, the flow of the story was just right, and the production quality was also good. I can see why Douban gave it such a high rating. It is a 9.0 rating for me as well.
