TL;DR: The legend of bánh chưng and bánh giầy is a folk tale about Lang Liêu, son of the sixth Hùng Vương, who used glutinous rice to make two kinds of cakes and offered them to his father the king to worship the ancestral kings at the year's end. The story explains the origin of the custom of wrapping bánh chưng and bánh giầy at Tết and honours farming and filial piety in Vietnamese culture. The legend is recorded in the book Lĩnh Nam chích quái and does not appear in the official histories.
What is the legend of bánh chưng and bánh giầy?
The legend of bánh chưng and bánh giầy is a folk tale from the Hùng Vương era that explains why Vietnamese people wrap bánh chưng and pound bánh giầy to offer to ancestors at Tết. It tells of Lang Liêu, a prince in the sixth Hùng Vương era, who won the throne because of two cakes made from glutinous rice. This is a legend, not a historical event with verified evidence; modern scholarship treats it as a product of folk imagination explaining a long-standing custom. The legend is recorded in Lĩnh Nam chích quái, a collection of tales in classical Chinese revised by Vũ Quỳnh and Kiều Phú at the end of the 15th century, under the title Chưng bính truyện[4]; literary scholars also mention it as one of the myths about the custom of wrapping bánh chưng and bánh giầy among wet-rice farmers[1].
A distinction is needed between two layers: the story (a folk legend) and the custom (wrapping bánh chưng and bánh giầy at Tết, which is real in daily life). The story explains the custom but is not historical evidence for events in the sixth Hùng Vương era. Phan Kế Bính's Việt Nam phong tục (1915) records bánh chưng and bánh giầy as two of the most important cakes in worship and in life-cycle ceremonies of Vietnamese people in the early 20th century[2].
Who is Lang Liêu in the story?
According to Lĩnh Nam chích quái, after defeating the Ân invaders, Hùng Vương wished to pass on the throne. He gathered his twenty-two sons and said that whoever found fine and rare foods to offer to the former kings at the end of the year, so as to fulfil filial duty, would receive the throne. The sons vied to find treasures from land and water. Only the eighteenth son, Lang Liêu, whose mother was of humble standing and had already died, had few people to help him and could hardly manage[4]. The classical Chinese text does not say which Hùng Vương this was; popular retellings today make him the sixth.
That night Lang Liêu dreamed that a spirit told him: nothing in heaven and earth is more precious than rice; take glutinous rice and make cakes, one square and one round, to image heaven and earth, wrap them in leaves with fine food inside, to signify the debt owed to parents for birth and upbringing. He chose pure white glutinous rice, wrapped it in green leaves into a square with fine food in the middle, and cooked it, calling it bánh chưng; he also steamed glutinous rice, pounded it smooth, and shaped it round, calling it bánh giầy. On the day, the king found them better than everything the other sons offered, asked about them, and Lang Liêu told of the dream; the king ranked Lang Liêu first and passed him the throne[4].
Why is bánh chưng square and bánh giầy round?
Bánh chưng is square to represent the earth, and bánh giầy is round to represent the sky, according to the explanation in the story. This is the legend's interpretation, not a mandatory rule in all periods. In the Lĩnh Nam chích quái text, the spirit also says that the leaf wrapping outside and the fine food inside signify the debt owed to parents for birth and upbringing[4]. In folk belief, people still pass down that square bánh chưng is the earth and round bánh giầy is the sky, and the two cakes symbolize the harmony of heaven and earth.
In which books was this legend recorded?
The legend of bánh chưng and bánh giầy is recorded in Lĩnh Nam chích quái, in the tale Chưng bính truyện[4]. Twentieth-century books on customs and essays record how the two cakes were used in daily life. Phan Kế Bính's Việt Nam phong tục (1915) states that bánh chưng and bánh giầy are the two most important cakes in worship and life-cycle ceremonies, used as gifts during seasonal festivals and death anniversaries[2]. Thạch Lam's Hà Nội băm sáu phố phường (1943) also mentions the round bánh giầy of Quán Gánh as a special local treat[3].
However, note: these books only prove that the custom of wrapping bánh chưng and bánh giầy existed and was recorded in Vietnamese life; they do not prove the Lang Liêu legend is a historical event. Modern literary scholarship treats the myths about wrapping bánh chưng and bánh giầy as products of folk culture, reflecting the Tết of wet-rice farmers since the Hùng Vương era[1].

Why are bánh chưng and bánh giầy associated with Tết?
Bánh chưng and bánh giầy are associated with Tết because they are offerings to ancestors, expressing filial piety and gratitude for origins. In the Vietnamese mind, Tết is a time for family reunion and remembering ancestors, and bánh chưng and bánh giầy are indispensable on the altar. Phan Kế Bính's Việt Nam phong tục (1915) records that bánh chưng and bánh giầy are used during seasonal festivals, death anniversaries, and even weddings[2]. Literary research on Tết in Vietnamese literature after 1986 also surveys a number of essays about the pot of bánh chưng and the wrapping of cakes at Tết[1].
Variants and different details
Comparing the classical Chinese text in Lĩnh Nam chích quái with popular retellings today shows several differences. The classical text does not say which Hùng Vương it was, does not name the filling or the leaves, and says the offering was for the former kings at the end of the year; popular retellings usually add mung beans, pork and dong leaves and set the story under the sixth Hùng Vương. At the end, the classical text also records that after Lang Liêu succeeded, his twenty-one brothers each held a region as a protective fence for the realm[4].
The common point of the variants is: Lang Liêu used glutinous rice to make two cakes, offered them to his father, and was given the throne. This common point shows the core of the story is honoring farming and filial piety, not fighting for the throne by force. This is a beauty in Vietnamese culture: the successor is not the strongest, but the one who understands the value of rice and of heaven and earth.
Nhật Nguyệt's suggestions
Nhật Nguyệt's suggestions: when learning about the legend of bánh chưng and bánh giầy, one should read the story as a folk legend, not as historical record. The legend explains the custom, while the custom is real in life. Wrapping bánh chưng and pounding bánh giầy at Tết is a way to preserve cultural beauty, not a mandatory act to receive blessings or luck.
