Dong Da festival takes place on the January 5th of the first lunar month. This is a victory festival, held in memory of the glorious achievements of Quang Trung King – the hero in history against invaders of the nation.

Two centuries ago, Dong Da was a battlefield where Quang Trung (Nguyen Hue), a Tay Son farmer who later became a National Hero defeated more than 200,000 soldiers of the Qing invaders. Dong Da Hill became a glorious historical site of the Vietnamese nation.

Ever since, on the 5th of the first lunar month, Ha Noi people hold a festival to celebrate this historic victory.
