Wei Jinyi, the exclusive military and political intelligence agency of the Ming Dynasty, was formerly known as "Gong Weisi" established by Zhu Yuanzhang, the founding emperor of the Ming Dynasty, and later renamed as "Pro-military Dewey House", in charge of the etiquette duties and guards of Yiluan Division and the emperor. In the fifteenth year of Hongwu (1382), the pro-army Dewey House and Yiluan Division were abolished and changed to Royal Guards. As the military organization of the Imperial Guard, the Royal Guards' main functions are "commanding guards, patrolling and arresting". Its leader is called the Commander of the Royal Guards, who is generally served by the Emperor's close military commander and is directly responsible to the Emperor.
