All I can say is that the show was not really worth watching. I thought it would of added more history versus a love triangle that made no sense. Less focus on the evil that people were doing and more focus on the true story. I couldn't even watch it till the end.
As for the actors they were for a better lack of words mediocre. (I don't want to offend anyone who loves Wallace Huo he's okay) but i felt like the story line really had no heads or tails to make sense.
The only two actors that I really loved in this series was the Oriat that wanted to marry the main lead, and the emperor who clearly loved her and couldn't have her.
Not worth watching again either. Sorry
