Yaya is the eldest daughter of Qin Shizhong, a wealthy businessman in Tongcheng, and was born to his wife. Just because the wife of the first wife had a difficult delivery, Qin Shizhong regarded Yaya as a little disaster, beat and scolded him at every turn, and was particularly partial to his concubine and his daughter Qin Yueyue. The Qin Mansion encountered disasters one after another, which even endangered Qin Shizhong's life. After the crisis, he attributed the credit of turning danger into safety to the fake lucky star Qin Yueyue, and expelled Yaya, who really brought his own good fortune, from the Qin Mansion. The governor's wife Zhou Yanjun rescued Yaya with her five-year-old aphasic son Fu Qingzhao and renamed her Zhouzhou.
