Trịnh lords
Later, Trương Văn Hiến encouraged Nguyễn Nhạc to revolt against Nguyễn lords: "The prophecy says: 'Revolt in the West, success in the North'. You are born in Tây Sơn District, you must do your best." Nguyễn Nhạc then gathered people to help him in his rebellion, saying to "overthrow the Trịnh lords, revive the Lê dynasty".
