a prince of the sixth Hùng Vương, who became Hùng Vương's successor thanks to his creation of bánh chưng and bánh dày, which symbolized respectively the Earth and the Sky. Considered an essential element of the family altar on the occasion of Tết, the making and eating of bánh chưng during this time is a well-preserved tradition of Vietnamese people. Beside the Tết holiday, bánh chưng is also eaten all year round as a delicacy of Vietnamese cuisine and one of the national dishes of Vietnam besides chả giò and phở.
