This story tells about Yu Xing (Wu Jiayi) and her adventures in the palace as cook and later as a physician to protect her sister in the palace.

She is strong heroine and determination, has a influential boyfriend in the palace and well...some family secret later on
Is actually a light hearted comedy drama like a a fanfiction with a strong heroine in my opinion.

There is nothing deep, political intrigue is shallow.
If you are hoping for Yanxi style drama not here, much better to go see Winter Begonia for that melancholy,
this drama is just a modern comedy set in the Qing dynasty ( the characters behave in quite modern way, if this was Yanxi they would have been beheaded or sent to the prison)

Wu Jiayi is always willing to play the comical character
