Quick questions on The Confucian state and administration in Qin and Han China: HSC Ancient History

At the centre of Han government stood the Three Excellencies (Sangong), also translated as the Three Lords: the Chancellor (Chengxiang), who headed the civil bureaucracy; the Imperial Counsellor (Yushi Dafu), deputy chancellor and chief of the censorate, who supervised officials and kept the records; and the Grand Commandant (Taiwei), nominal head of the armed forces, an office often left vacant and its power absorbed into a regent's title such as Grand Marshal (Da Sima). Beneath them the Nine Ministers (Jiuqing) ran the specialist departments - justice, ceremonies, finance, foreign relations, the imperial household and more - a far more elaborate central administration than any earlier Chinese state.
