Liu Zi (劉滋; 729 – November 19, 794[1][2]), courtesy name Gongmao (公茂), was an official of the Chinese Tang dynasty, briefly serving as a chancellor during the reign of Emperor Dezong.
Thereafter, the deputy minister of civil service affairs, Yang Wan, recommended him as someone who can serve as an advisor to the emperor, and so he was recalled to be Zuo Bujue (左補闕), a low-level official at the examination bureau of government (門下省, Menxia Sheng).
After the period of mourning was over, he was recalled to the imperial government to serve as Tuntian Yuanwailang (屯田員外郎), a low-level official at the ministry of public works (工部, Gongbu).
[7] Liu Zi followed him there, and served as deputy minister of worship (太常少卿, Taichang Shaoqing), in charge of ceremonies.
[4] In 786, Liu Zi was made Zuo Sanqi Changshi (左散騎常侍), a high-level consultant at the examination bureau, and given the designation Tong Zhongshu Menxia Pingzhangshi (同中書門下平章事), making him a chancellor de facto, along with Qi Ying and Cui Zao.
[9] Soon thereafter, Liu was indicted by imperial censor Wei Zhenbo (韋貞伯) for having been insufficiently selective when selecting officials at the ministry of civil service affairs, and he, while not demoted, was stripped of the privilege of wearing gold and purple as due an official of his rank, along with his deputy minister Du Huangchang.
