The Association of Phet Hien Quan has been maintained for more than a thousand years, including the years when the country was still at war. The festival aims to honor and show the martial spirit, to commemorate the great merits of female general Thieu Hoa and her generals and insurgents, thereby educating patriotism, pride, national pride and the indomitable tradition of the nation in the cause of national construction and defense.
