Zhang Guoguo (played by Sun Yi) is a delivery girl of a wonton shop that is familiar to the neighbors. She has won everyone's love and respect with her enthusiasm and cheerfulness. In fact, Zhang Guoguo's true identity is the daughter of the famous Suzhou embroidery workshop Jinluoge. Although she does not know her life experience, blood and genes will not lie. Zhang Guoguo showed extraordinary talent in embroidery, and finally overcame all difficulties and entered Jinluoge as an apprentice with her own efforts. Although Zhang Yuxin (played by Wu You) and Zhang Guoguo have no actual blood relationship, they grew up under the same roof, and Zhang Guoguo has always regarded each other as her own sisters. Who knows that greed and desire blinded Zhang Yuxin's eyes, and she worshipped Xu Huijie (played by Pan Yijun) as her teacher, and Xu Huijie is Zhang Guoguo's biological mother. In career, Zhang Yuxin has become Zhang Guoguo's strongest competitor, and in terms of feelings, they are also caught in the entanglement of the same pair of brothers.
