I have watched many historical dramas and this one sits at the top, the best I've ever watched. 70 episodes seemed like a huge commitment of your time to undertake but Chinese dramas, unlike the American ones, do not split their shows into Season 1, Season 2, and so forth. The dialogues are lyrical with a lot of hidden sarcasm and insinuations. Superb acting by every actor (esp the King, his eunuch, headmaster Xin & Feng Zhiwei). I didn't like Chen Kun's acting, he tried too hard that it looked exaggerated and theatrical. The chemistry between the two main casts Chen Kun & Ni Ni was off the charts.
Although I really hate the ending, it was poetic. However, I did not like the last 20 episodes especially with Feng Zhiwei's brother, it just didn't make sense.
