Ziwei (Ruby Lin) and her maid Jinsuo (Fan Bingbing) brought the token that Qianlong (Zhang Tielin) left for her mother and came to Beijing from Jiangnan to meet Qianlong. They found that they had no way to enter the palace to meet the emperor. When they were desperate, they met the female thief Xiaoyanzi and became friends with her. However, by chance, Xiaoyanzi, who was eager to help Ziwei, was mistaken by Qianlong as his daughter. In order to celebrate the return of his beloved daughter, Qianlong held a ceremony to offer sacrifices to the gods. When the ceremonial team passed through the streets, Ziwei and Jinsuo saw it. Ziwei was too excited and fainted on the ground. She was rescued by Fu Erkang (Zhou Jie), the son of Grand Secretary Fulun. After learning about Ziwei's life experience, the Fu family took her in. Later, Ziwei finally met Xiaoyanzi again under Fu Erkang's arrangement. Everyone began to make various arrangements for Ziwei and Qianlong to recognize each other. In this process, Ziwei and Fu Erkang, Xiaoyanzi and the fifth prince Yongqi (Alec Su) also began their love journey.
