Zhang Zuo
After Zhang Chonghua died in 353, his son Zhang Yaoling carried the Jin Dynasty (266–420)-created title Duke of Xiping and was the titular ruler, but actual power was in Empress Dowager Ma's and Zhang Chonghua's older brother Zhang Zuo's hands. Most historians believed that she had an affair with Zhang Zuo, and later that year, she deposed Zhang Yaoling and replaced him with Zhang Zuo.
