九卿
The Excellency of Works, also known as the Minister of Works, was less powerful than his previous counterpart, the Imperial Counselor. This official's advisory and censorial responsibilities coincided with those of two other Excellencies, forming a tripartite cabinet arrangement. Unlike the abolished Imperial Counselor, he was given the specialized role of overseeing public works projects throughout the empire. The Excellency of Works was responsible for the construction of city walls, towns, canals, irrigation ditches, dykes and dams, and other structural engineering projects. The Court Architect supervised only imperial building projects. The Excellency of Works made annual reports to the throne about the progress of local administrations' conduct of construction projects. He was given formal powers to supervise three of the Nine Ministers: the Minister of the Imperial Clan, Minister of Finance, and Minister Steward.
