As many of us, I started watching because of Tan Jianci. I was so sad after LYF... but as soon as I started Go East, I started smiling. What an amazing actor he is, his character, Yuan Mo, is so different and he simply rocked it.

What did I like?
The story. It was full of suspense and mystery, I liked the rivalry of the two courts, the way the ML and FL interacted.
I also had my part of heartbreak.
What I loved most was Yuan Mo (Tan Jianci). His love for Ah Shu was so pure and earnest, he was wonderful. I also loved his wit, he was always so clever, I laughed aloud during his funny moments, I also loved the fact that he was not a warrior.
The mysterious Man in White was a great villain.

What did I like less?
The hairdo if the people of Mobei. I liked Prince Duomi (well, probably because I think Xu Hai Qiao is cute), but what were those snakey things beside the cheeks of the Mobei people?
I didn't like the fact that sometimes something incredible happened and in a flash-back we got many informations to explain it afterwards ton make it work.
Some of the villains, as Mutu, were portrayed as to dumb.
The sidestories were ok, but not exhilarating, I think there was place for more. A soon as the story switched back to the main couple, I almost forgot them.

In my opinion it was Tan Jiancis performance who made this drama such a good watch. Without him it would have been average.
But as it is, you won't regret if you watch it.
