To display her high moral standards, Cixi executed only three of the eight regents. Prince Gong had suggested that Sushun and others be executed by the most painful method, known as slow slicing ("death by a thousand cuts"), but Cixi declined the suggestion and ordered that Sushun be beheaded, while the other two also marked for execution, Zaiyuan and Duanhua, were given pieces of white silk for them to hang themselves with. In addition, Cixi refused outright the idea of executing the family members of the regents, as would be done in accordance with imperial tradition of an alleged usurper. Ironically, Qing imperial tradition also dictated that women and princes were never to engage in politics. In breaking with tradition, Cixi became the only empress dowager in the Qing dynasty to assume the role of regent, following a practice known as "ruling from behind the curtains" () in Chinese.
