As a Chinese, I have seen 90% of Chinese movies and drama to be bad overall. They concentrated to much on fighting.
This story is confusing, don't make sense, terrible actors and actress. Low budget production etc. I quit watching after 30 episodes.

How does the oldest princess turned evil and tried to kill her younger sister?
No Plot
Honestly it is made for under 10 grade audiences.
Actors and actresses are over 30 years old who played 16 years old or 20 years old.
