China's sister in the past was too poisonous, because she wanted to keep her position and to maintain her authority. In the TV series "The Past of China", my great-aunt Sanqiu has shown an introverted personality since she gave birth to a child, especially comparing her second great-aunt with Xiaoyu. Sanqiu may be because of his inner kindness, or because he thinks that his aunt's identity is not car-scrapping, and he is the most calm and restrained person except the eldest housewife. But these forbearance always broke out in the end, so they killed Dao.
