Query: Which ethnicities made up the Qing government?
Context: The formal structure of the Qing government centered on the Emperor as the absolute ruler, who presided over six Boards (Ministries[c]), each headed by two presidents[d] and assisted by four vice presidents.[e] In contrast to the Ming system, however, Qing ethnic policy dictated that appointments were split between Manchu noblemen and Han officials who had passed the highest levels of the state examinations. The Grand Secretariat,[f] which had been an important policy-making body under the Ming, lost its importance during the Qing and evolved into an imperial chancery.
