Nine Ministers
Emperor Gaozu initially made Luoyang his capital, but then moved it to Chang'an (near modern Xi'an, Shaanxi) due to concerns over natural defences and better access to supply routes. Following Qin precedent, Emperor Gaozu adopted the administrative model of a tripartite cabinet (formed by the Three Excellencies) along with nine subordinate ministries (headed by the Nine Ministers). Despite Han statesmen's general condemnation of Qin's harsh methods and Legalist philosophy, the first Han law code compiled by Chancellor Xiao He in 200 BCE seems to have borrowed much from the structure and substance of the Qin code (excavated texts from Shuihudi and Zhangjiashan in modern times have reinforced this suspicion).
