Speaking of the Dragon Boat Festival in China, why eat zongzi? In fact, our ancestors learned to cook food with fire very early. It used to be a common food custom to wrap food with leaves of big-leaved plants, cook them in fire or peel them in boiling water. It usually occurs in the south where large-leaved plants are widely distributed. Just like storing rice in a newly cut bamboo tube and grilling mature food on a fire, it belongs to an ancient method for southern rice growers to make food. There is also the May Festival, also called "Summer Solstice Festival to eat jiaozi, and the surrounding area is called corn millet." Corn in the north and rice dumplings in the south are collectively called rice dumplings. They used to be sacrifices for the Dragon Boat Festival and were used to commemorate Qu Yuan in the Southern and Northern Dynasties. In the Tang Dynasty, the millet in the north was gradually replaced by glutinous rice, which spread to the folk culture of eating zongzi on the Dragon Boat Festival. This is why there is a custom of making zongzi on the Dragon Boat Festival.
