Cui Shi
Wu Sansi was very happy and invited Zheng up a tower, to further discuss with Zheng the strategies he should take. He further recommended Zheng to serve as "Zhongshu Sheren" (中書舍人), a mid-level official that legislative bureau of government (中書省, "Zhongshu Sheng"). Zheng thereafter served as chief strategist for Wu Sansi, along with Cui Shi. Soon, Wu Sansi and Empress Wei were able to persuade Emperor Zhongzong to remove the coup leaders from their chancellor posts under guise of honoring them with princely titles.
