This collection of 78 documents in Chinese and Nom characters (Sino-Nom) was carved on cliffs and caves, with variety in content and literary genres, created by kings and mandarins of the Nguyen Dynasty, as well as venerable monks and intellectuals, dating from the first half of the 17th century to the 20th century. They store the “memories” of the economic, cultural, political and social contacts between Vietnam and other countries on the maritime route across the region as well as the role of Vietnamese women in international marriages in the 17th century.
