Not a bad drama. Ning Jing is a great female fighter like usual. Same goes with Huang Haibing, he is manly and handsome. Love the way how he always fight with real kungfu (I doubt he's any experienced at all) but he is so good at imitating kung fu movements and forms that will make him look real and really legit.
He always rides his horse like a hero (in every drama he's in)! He should be awarded as the best horse rider.
It is a great pairing. Both the lady and man are strong and good at martial arts.

Huang Haibing character here is lovely. I really like his portrayal of Shen Lang from Wulin Waishi. In here, I can see a bit similarity except that he added a bit more silly, fun, playful, cute side to himself. Shen Lang was playful too but the character in here he plays less smart and less witty, sometimes he would smile like an idiot and looks cute. He is still mostly serious but once in a while he will get non-serious and funny.
I love love love the relationship between Huang Haibing and his mom in here, reminds me of Jet Li's Fong Sai Yuk or Jackie Chan & Anita Mui's Drunken Master II. He's super duper adorable around his mom. The drama overall has few parts that are boring, but I still don't skim this as excessively as how I skim new dramas today. Even the ugly villains in here have very high watching value. If I were to rewatch this I would rewatch all the scenes with Huang Haibing and his mom together.

Wu Jia Ni is adorable, all the other ladies are pretty and adorable as well.

Lots of history I learned in this show.
During the Ming dynasty, there is a group of secret police call Jinyi Wei.

Jinyi Wei is a massive group of people, they protect the king so whoever is a Jinyi wei has a really high status. Rumors say they are allowed to kill anybody without explanations or under the disguise that the people they killed have done/said rebellious things.

Huang Haibing's character plays as a secret police, he is very proud of it until he learns how corrupt the system is. He protects the young king and is a very good friend or brother with him. The king, like in history, he has a learning disability and has no interest in politics but carpentry.

The actor for the king did pretty well, he is nice but very unintelligent that it led to the eunuch Wei Zhongxian (most powerful eunuch in history) to seize full power and control.

Dislikes: The Jinyi Wei uniforms look so ridiculous! Make the guys look ugly and funny. All other clothings are good.
Likes: The music, I love all the OST in here very much.
