阮攸
After passing the provincial exam, he was appointed to the position of a military advisor in the Royal (Trịnh) army. After the Trịnh lords were defeated in 1786 by Nguyễn Huệ (the second youngest, most able and popular of the three Tây Sơn brothers), Nguyễn Du refused to serve in the Tây Sơn administration. He was arrested and held for some time before moving back to his native village in the north of the country.
