Lê Lợi
Trịnh Khả, like most of Lê Lợi's chief aids and generals, was from Thanh Hóa Province which is where Lê Lợi was born. During the decade-long Lam Sơn uprising against the Ming dynasty, Trịnh Khả served as an advisor to Lê Lợi. With victory, Trịnh Khả was elevated to a high position in the new court of Emperor Lê Lợi. Trịnh Khả (and the other councilors) were given the privilege of wearing red silk and were called Hành-khiển. Other members of this new elite were: Nguyễn Trãi, Tran Nguyen Han, Lê Sát, Phạm Văn Xảo, Dinh Liêt, and Lê Ngan.
