Origin of Zongzi:

The Zongzi is one of the traditional Han Chinese festival foods, which is made by utilizing staple materials such as round-grained rice, glutinous rice, etc., wrapped in plant leaves such as bamboo leaves, lotus leaves, etc., and then cooked by steaming, boiling and baking. With its delicate, fragrant and glutinous taste, and moderate saltiness and sweetness, zongzi is one of the traditional Chinese delicacies.

There are different legends and historical records about the origin of zongzi. One theory is that the zongzi originated from the ancient dragon boat racing activities, and another is that the zongzi originated from the ancient sacrificial activities.

According to traditional cultural and historical records, zongzi first appeared in the Spring and Autumn and Warring States Periods as a kind of sacrificial offerings for ancestors and gods. According to the Zhou Rites, during the Zhou Dynasty, nobles would offer sacrifices to their ancestors and gods during the Dragon Boat Festival and use zongzi as offerings.

Besides the rituals, there is also a legend that the dumplings are related to Qu Yuan. According to legend, Qu Yuan was a famous patriotic poet in Chinese history who threw himself into the river after being relegated in Chu. In order to prevent fish and shrimp from eating Qu Yuan's body, people put zongzi into the river to scare away the fish and shrimp. Later, this custom developed into one of the important food items of the Dragon Boat Festival.

In short, zongzi is one of China's traditional Han festival foods with a long history and cultural background. It originated from ancient rituals and dragon boat races, and is an integral part of traditional Chinese culture.
