The Cold Foods Festival: Origins and Vietnamese Transformation
The Cold Foods Festival (Tết Hàn thực) falls on the 3rd day of the 3rd lunar month. Its Chinese origin relates to Jie Zitui, a loyal retainer of Duke Wen of Jin during the Spring and Autumn period. When the duke was in exile, Jie cut flesh from his own thigh to feed him. After the duke regained power, Jie refused rewards and retreated to a forest with his mother. The duke ordered the forest burned to force him out, but Jie perished in the fire. To honor him, the duke decreed three days without fire, hence eating only cold food.
However, when this festival arrived in Vietnam, it was deeply localized. Vietnamese people do not abstain from fire or eat cold dishes. Instead, this day became an occasion for families to make bánh trôi and bánh chay (glutinous rice cakes) to offer ancestors, embodying the principle of "remembering one's roots."
Bánh Trôi and Bánh Chay: Subtle Differences
Both cakes use glutinous rice flour but differ significantly:
Bánh Trôi
Bánh trôi are small, round balls with a core of brown sugar (cane sugar). When boiled, they float to the surface, inspiring the folk saying "bánh trôi floats, bánh chay sinks." They are typically rolled in toasted sesame or shredded coconut. This cake is famously linked to poet Hồ Xuân Hương's verse about women's fate in feudal society.
Bánh Chay
Bánh chay are larger, with thicker dough and often filled with mashed mung beans or left unfilled. After boiling, they are served in a bowl with ginger syrup, creating a warm, mildly spicy sweetness. Unlike bánh trôi, bánh chay is always eaten with syrup.
| Feature | Bánh Trôi | Bánh Chay |
|---|---|---|
| Size | Small, round | Larger, flatter round |
| Filling | Brown sugar | Mung bean or none |
| Serving | Dry with sesame/coconut | With ginger syrup |
| Boiling behavior | Floats | Sinks |
Spiritual Meaning and Offering Customs
On the morning of the festival, Vietnamese families wake early to prepare ingredients and make cakes together, strengthening family bonds. After boiling, cakes are arranged on plates with water and fruits on the ancestral altar. The white color symbolizes purity, and the round shape represents completeness. Offering these cakes expresses gratitude and filial piety toward ancestors.
Differences Between Vietnam and China
- Nature: In China, it is a day to honor Jie Zitui by avoiding fire and eating cold food. In Vietnam, cooking proceeds normally.
- Main activity: Chinese people visit and clean ancestral graves. Vietnamese focus on making cakes for home offerings.
- Meaning: Vietnamese do not view this as a somber day but as a joyful family gathering.
This creative localization transformed a foreign custom into a distinctly Vietnamese cultural trait centered on family and ancestry.
The Festival in Modern Life
In contemporary urban life, many young families buy ready-made cakes from stores instead of making them at home. However, many still preserve the tradition of homemade cakes, using the occasion to teach children about heritage, skill, and filial piety. Whether homemade or store-bought, maintaining this custom reflects Vietnamese respect for spiritual values and national identity in an era of globalization.
