An exhibition of royal documents bearing the handwritten comments and signatures of the 10 Kings under the Nguyen Dynasty opened in the former imperial city of Hue on September 20.

On display are more than 150 documents, which were drafted by administrative agencies from local to central levels, and then submitted to the Kings for considering and approving. They covered many issues from politics, military, diplomacy, to economics, culture and society.

They are reliable materials for the study of the administrative system as well as the culture, history and art of the Nguyen dynasty, said Director of the Hue Relics Preservation Centre Phan Thanh Hai.

The ongoing exhibition, the first of its kind in Hue, is part of activities to mark the 20 th anniversary of recognition of the Hue imperial relic complex by UNESCO as a World Cultural Heritage Site and the 90 th founding anniversary of the Hue Royal Antiquities Museum.-VNA
