Here is a synopsis:
Throughout the drama, she is a palace maid. She forms a hate-hate relationship with the eighth prince at first. This caused her to be tortured by other palace maids and bullied. However she also made friends with a palace maid that actually liked the fourth prince. Qing Chuan, though bullied, never takes it to heart and never tries to find revenge at the people who always bully her. As the drama goes on, she falls in love with her favorite historical figure, the fourth prince, who is the future emperor. However, she learned that history books aren't specific about the full details of life in the Qing dynasty and leaves the fourth prince. She begins to form a closer relationship with the eighth prince as the eighth prince falls in love with her and takes care of her from harm.
This drama has a lot of women such as the emperor's concubines and also the fourth prince's wife. So there was a lot of jealousy between those women. Unlike "Bubujingxin," Qing Chuan does not affect history in any way or alter it. Her wit and knowledge makes her the person caught in the competiton for the throne and between the fourth and eighth prince. There was even a weird twist in the drama at one point. As for what happens next, I hope that you will watch it and just enjoy the humor of this drama. However, if you want something more realistic and easier to connect in many levels, I still recommend the drama Bubujingxin.
Personally, in this drama, I liked the eighth prince more than the fourth prince because the fourth prince kept on trying to kill her. Also, the eighth prince had a great connection with her in this drama. I loved the chemistry.
In Bubujingxin, I thought all the princes were brilliant in their own ways. So therefore, I felt Bubujingxin was better in many ways.
