Zhang Zuo
Zhang Zuo was a violent and frivolous ruler, and there was soon much opposition against him, particularly after he completely broke away from Jin Dynasty (266–420). In 355, the generals Zhang Guan and Song Hun rebelled against Zhang Zuo and announced that they wished to restore Zhang Yaoling. In response, Zhang Zuo executed Zhang Yaoling by beating him to death. Zhang Zuo, however, would soon be overthrown and replaced by Zhang Yaoling's younger brother Zhang Xuanjing.
