Tiger Mom Rules ( 虎妈驾到，全家反骨仔乖乖立正)

Butcher Lin Yingchun (Grace Linwood) is suddenly hunted down by debt collectors for a 500,000 yuan online loan she never took out. She discovers it was the work of her long-lost twin sister, Lin Wanqiu. Dying of cancer, Wanqiu used the debt as a way to find her sister—and to entrust her with the care of her three troubled children. Yingchun takes her sister's place in the Zhou family, where she confronts her sister's husband, his mistress, and her mother-in-law—and begins to set the three rebellious children straight. Using her own unique ways, she gradually straightens out the family's unhealthy atmosphere, teaching the three rebellious children to "stand at attention" through a mix of fear and love. From a butcher to a stepmother, Lin Yingchun proves with her most straightforward approach that no child is too wayward to be won over by a sincere heart.
