The Cold Food Festival: From Chinese Legend to Vietnamese Custom
The Cold Food Festival (Tết Hàn Thực) falls on the 3rd day of the 3rd lunar month and is known in Vietnam as the day of bánh trôi and bánh chay. The name "Hàn Thực" means eating cold food, originating from a Chinese legend about Jie Zitui, a loyal retainer who served Duke Wen of Jin during his 19 years of exile, even cutting flesh from his thigh to feed the starving duke. After regaining power, the duke forgot Jie's merits, so Jie retired to the forest with his mother. When the duke remembered and set the forest on fire to force him out, Jie and his mother perished on the 3rd day of the 3rd lunar month. Grief-stricken, the duke ordered people to abstain from fire for three days and eat only cold, pre-cooked food.
Vietnamese Localization: No Fire Taboo, Only Ancestor Worship
Although the festival was adopted, Vietnamese people largely dropped the fire taboo and abandoned the memory of Jie Zitui. Scholar Phan Cẩm Thượng, citing Lê Quý Đôn, notes that ancient Vietnamese used fried cakes, not bánh trôi bánh chay. Author Nhất Thanh in "Đất lề quê thói" called these cakes "poetic cakes," linked to Hồ Xuân Hương's verse, with no connection to the Chinese Han Thuc legend. Researcher Huỳnh Ngọc Trảng places the festival among the four seasonal rites, often simple with fruits and sweets.
In practice, Vietnamese families worship ancestors on this day, not Jie Zitui. The common saying "it bears the name Han Thuc but cooking is not avoided" reflects cultural creativity: borrowing the calendar time but filling it with Vietnamese content, directing hearts toward ancestors and roots.
Bánh Trôi, Bánh Chay: Symbols of Wet-Rice Civilization
Bánh trôi are small glutinous rice balls with palm sugar or mung bean filling, boiled until they float, then coated with sesame. Bánh chay are larger, flatter, with mung bean filling, served in ginger syrup. Both are made from glutinous rice, reflecting the ancient wet-rice civilization and honoring farmers' labor.
Beyond food, these cakes carry deep symbolism. In the legend of the Dragon and Fairy, bánh trôi represent the 50 children who followed mother Âu Cơ to the mountains, while bánh chay represent the 50 children who followed father Lạc Long Quân to the sea. The round shape signifies fullness and purity, and the pairing of bánh trôi (yang) and bánh chay (yin) embodies harmony and balance.
According to culinary artisan Hiền Minh, the festival is most prominent in the North; the South rarely observes it except for Northern-origin families, while the Central region often offers fruits. The day is also an occasion for family reunion, making cakes together, and offering incense to ancestors.
Offering Tray and Cake-Making Tips
A traditional Northern offering tray includes bánh trôi, bánh chay, xôi, fresh flowers, betel and areca, five-fruit tray, and clean water. Some families add other traditional sweets. Freshly ground glutinous rice flour gives the best texture, as shared by Hanoian Vũ Thu Hương. For perfect cakes, knead with warm water, add sweet potato for softness, and boil gently after they float to avoid breaking.
Spiritual Meaning and Continuity
The Cold Food Festival in Vietnam is a time to express gratitude to ancestors, connect past and present, and reinforce cultural identity. Despite modernization, the custom persists, even among overseas Vietnamese, as shown by Kỳ Duyên making traditional cakes abroad to ease homesickness. This transformation from a fire-abstinence rite into a day of ancestor worship with bánh trôi and bánh chay demonstrates the resilience of Vietnamese culture: selectively adopting foreign elements, turning them into something uniquely Vietnamese, both solemn and familiar.
