A high fever took away the Wang sister's biological daughter and gave her a "daughter" who hid a royal secret - the baby girl picked up by Feng Xueye turned out to be the Queen's lost little princess. She raised the baby girl as her own daughter, supported each other with her sister who guarded the village and had a daughter, and waited for her husbands who returned from the border crossing and narrowly escaped death.
The queen's search team disturbed the peace of the countryside, and the selfishness of her brother-in-law turned the pursuit into a farce. When the sister's daughter took the initiative and lied that she was a princess, everyone thought it was a drama that was difficult to distinguish between true and false. Only the queen could see through it. She accepted the fake princess and sent her to the border to get married, in exchange for a stable family. But the real little princess was kept by her side, and she did not have to be involved in court disputes, and could only live a happy life as an ordinary noble girl. From the cloth village of Qinghe Town to the palace walls of the capital, the mystery of the real and fake princess is ultimately a game of choice.
