On display are numerous documents and around 100 maps in Chinese, Nom (old Vietnamese writing using Chinese characters), French and modern Vietnamese, issued from the 17th to the outset of the 20th century by the Vietnamese feudal states and the French government in Indochina (on behalf of the then Vietnamese state). 

Worthy of note is a collection of four atlases and 30 maps compiled and published by China through historical periods, which prove China has never managed the islands. The four atlases also defined Hainan Island as China’s southernmost point. 

The event, organised by the province and the Ministry of Information and Communications, helps raise awareness among all Vietnamese people, particularly the younger generation, on patriotism, national unity and a sense of responsibility. 

The exhibition will remain open to visitors until June 11. 

This kind of exhibition has been organised in numerous provinces across the nation, including Vinh Phuc, Nghe An, Quang Nam, and Binh Phuoc.
