Grand chancellor (China)
The grand chancellor, also known by its Chinese name as zaixiang (宰相, variously interpreted as counselor-in-chief, chancellor, chief councillor, chief minister, imperial chancellor, lieutenant chancellor, and prime minister) is a generic blanket title identifying the highest-ranking ministers wielding both formal and actual authorities in the imperial Chinese government. Such ministers' titles varied over time and their responsibilities and actual authorities fluctuated widely throughout Chinese history, even within a particular dynasty or within the reign of a particular emperor.
