The three-day event aims to honour the great contributions of Tran Hung Dao, who acted as the Supreme Commander of Vietnam during the Tran Dynasty and led Vietnamese troops to repel three major Mongolian invasions in the 13th century.
Chairman of People's Committee of Quynh Phu district Pham Tien Thao said that the festival honours a glorious period in the country's history.
The event, which runs until March 12, will include an incense offering ceremony, a boat competition, art performances, folk games and folk dances.
The organising board will set up a corner displaying documentation and images of the A Sao National Historical and Cultural Site and develop a master plan for the site to be nominated as a Special national site in the future.
