阮攸
Created in the 13th century or earlier, the "Nôm" writing reached its zenith in the 18th century when many Vietnamese writers and poets composed their works in Nôm, most notably Nguyễn Du and Hồ Xuân Hương (dubbed "the Queen of Nôm poetry"). However, it was only used for official purposes during the brief Hồ and Tây Sơn dynasties.
