Qin Zhiyue, the famous Tigress of Lin'an, built up the Feng family's ten shops with nothing but a rolling pin. Before the wedding, she made a pact: if her husband took a concubine, they would divorce. In the end, Feng Jixuan brought Yaoniang home, and she merely smiled and said, "Fine." From then on, she taught her younger sister-in-law, Feng Ruyi, how to keep accounts and manage the shops while calmly preparing the concubine's welcoming ceremony. Everyone thought she had become a tame cat, but only Ruyi understood that she was waiting for the marriage contract to take effect. When the wine wore off, she was gone, leaving an empty house and a divorce agreement behind. That ray of light could never be caught again.
