The unruly princess Shengping (played by Guan Yonghe) is smart, enthusiastic and active. The emperor has always been worried that she has not found her ideal husband, so he decided to marry Shengping to the Uighur prince (played by Andy On). Shengping was very unwilling and fled with her maid. She came to Changlefang as a commoner and got to know the informal Guo Yan (played by Ouyang Zhenhua). At first, Guo Yan and others were very disgusted with Shengping's "princess temper", but later everyone experienced many twists and turns together. Especially Guo Yan and Shengping, the two of them showed their true feelings in adversity. After they returned to the palace, they officially got married, but the red tape and intrigue in the palace made Guo Yan feel stressed, and Shengping didn't know how to deal with the relationship between mother-in-law and daughter-in-law, which led to misunderstandings between the two. The discord between the couple was taken advantage of by the traitor, the Guo family was raided, and they were sent to the frontier. Shengping had to face the problem of marrying a foreign country again...
