Zhang Zuo
In 355, however, the overly extravagant and cruel Zhang Zuo was deposed and killed by a coalition of officials, including Zhang Guan (張瓘) and Song Hun, and they pressured her into making Zhang Chonghua's younger son, Zhang Xuanjing, the new ruler. Zhang Guan initially served as regent, but was killed in 359 by Song Hun, who served as regent until his death in 361. He was replaced by his brother Song Cheng (宋澄), who was in turn killed by Zhang Yong (張邕) later that year.
