同慶帝
After Nguyễn Văn Tường was exiled, Nguyễn Phúc Biện was enthroned as Emperor Đồng Khánh. But there were still many followers of Emperor Hàm Nghi. French general Chaumont was appointed to lead force into Quảng Bình to stop Tôn Thất Thuyết from going back to Tonkin. In 1886, Emperor Đồng Khánh began his northern tour to Quảng Bình, planning to convince Emperor Hàm Nghi and his followers to pay allegiance, but he failed. The same year, Emperor Đồng Khánh came back to Huế safely. Later he reinstated Hoàng Kế Viêm as Dong’ge Grand Secretariat, ordered him to convince Emperor Hàm Nghi and his followers to pay allegiance. But Hoàng Kế Viêm acquired no much success, coming back to court in 1887.
