Annually, thousands of visitors from all over the country participate in a national festival – Hung King Temple Festival. It is a ceremony in honor of Hung Kings, who were instrumental in the founding of the nation. The Hung King Temple Festival is held from the 8th to the 11th day of the third lunar month, but the main festival day is on the 10th. On that day, Vietnamese working people can have a day off. The main ceremony takes place at the Hung Temple on Nghia Linh Mountain in Phu Tho Province. Many ancient and modern flags are hung along the road to the temple. During the Hung Temple Festival, there are many folk games such as bamboo swings, rice cooking competitions, human chess,… Banh Chung (square cake) and Banh Giay (circle cake) are also prepared to remind people of the Lang Lieu Legend (the 18th Hung King who invented these cakes). It’s true that the Hung King Temple Festival is one of the most important and sacred festivals of the Vietnamese people.
