Looking for action drama series similar to Holyland

Hi fellows, I finished watching both Korean and Japanese versions of Holyland and I enjoyed both. So right now, I am looking for action drama series that are similar to Holyland, where the characters would give technical explanations about their fighting styles. For example, in Holyland, they really gave good and detailed explanations about the boxing jab-cross combo. Can be Japanese or Korean or Chinese. I don't mind.
