I mainly watched this because of Xiao Zhan: I will divide this review on whether is worth the time or not.

1: Yess, it is. because Xiao is in there as main cast. And not only that, he did an awsome job. One gets to love his character A LOT, more even thn the main male lead. So, he gets a decent amount of sreen time with a lovely elegant role.
If you have nothing else to watch, this drama is pure comedy. I laughed until my face was in pain.Thats why I actually watched the whole thing.

Cons:
You may get 2nd ale lead syndrome. To be honest at the end it was ok, since I rooted for the other fmale actress.

For a historial drama, it lacks a lot of seriousness. The plot is ok-ish but they I think they never intended it to be serious. As I said before, it is pure comedy and it is not intended to be taken seriously.But dont forget it is till a chinese series, it will also make you feel sad at times.
