Professor Zhu Zongbin of Peking University outlined the role of "grand chancellor" as one with the power to oversee all jurisdictional matters, the right to decide and to draft edicts with other ministers, and the position of chief advisor to the emperor.
During the Six Dynasties period, the term denoted a number of power-holders serving as chief administrators, including zhongshun jian (Inspector General of the Secretariat), zhongshu ling (President of the Secretariat), shizhong (Palace Attendant), shangshu ling and puye (president and vice-president of the Department of State Affairs).
[12] In 190, Dong Zhuo claimed the title "Chancellor of State" (相國) under the powerless Emperor Xian of Han,[13] placing himself above the Three Excellencies.
[16] In the Song dynasty, the post of chancellor was also known as the "Tongpingzhangshi" (同平章事),[17] in accordance with late-Tang terminology, while the vice-chancellor was known as the jijunsi.
The post was abolished after the execution of Hu Weiyong, who was accused of treason (though his conviction is still strongly disputed in present times because of a lack of evidence to prove his guilt).
The office of the Grand Secretariat assumed the de facto powers of the chancellery after the reign of the Hongwu Emperor.
Instead, the duties normally assumed by a chancellor were entrusted to a series of formal and informal institutions, the most prominent of which was the Grand Council.
