Every year on the fifth day of the fifth lunar month, people across China and many parts of East Asia gather to celebrate the Dragon Boat Festival, also known as Duanwu Festival. Among the most iconic and beloved customs of this celebration is the preparation and sharing of zongzi (粽子), also known in Vietnamese as bánh ú nước. These glutinous rice dumplings, wrapped in bamboo or reed leaves, hold deep cultural, historical, and culinary significance.

In this article, we will explore the origins of zongzi, their symbolism, regional variations, preparation methods, and the evolving role of these traditional treats in modern society. Whether you are a food enthusiast, cultural explorer, or someone reconnecting with your heritage, this comprehensive look at zongzi will offer insights into one of Asia’s most meaningful food traditions.
1. What Is Zongzi (Bánh Ú Nước)?
Zongzi are traditional Chinese rice dumplings made of sticky glutinous rice stuffed with various fillings and wrapped in leaves, typically bamboo, lotus, or reed leaves. They are usually triangular or tetrahedral in shape and steamed or boiled until tender.
The name bánh ú nước in Vietnamese refers to a particular variety of zongzi commonly enjoyed in Vietnam, especially during the Tết Đoan Ngọ (Vietnam’s version of the Dragon Boat Festival). “Nước” (water) in the name emphasizes the boiling process, while “bánh ú” refers to the pyramid-shaped glutinous rice cake.
2. Historical Origins: The Legend of Qu Yuan
The tradition of eating zongzi during the Dragon Boat Festival is deeply connected to the legend of Qu Yuan (屈原), a loyal and patriotic poet and statesman during the Warring States period of ancient China. Qu Yuan served the state of Chu but was exiled due to political intrigue. In despair over his country’s decline, he drowned himself in the Miluo River on the fifth day of the fifth lunar month.
According to legend, the local people admired and mourned Qu Yuan. They raced out in boats to search for his body—giving rise to the dragon boat races—and threw packets of rice into the river to feed his spirit and prevent fish from consuming his body. These packets of rice later evolved into zongzi.
Today, zongzi symbolize both an offering to a revered figure and a prayer for protection, prosperity, and family unity.
3. Symbolism of Zongzi
Zongzi are more than just delicious dumplings; they are rich in cultural symbolism:
