Yuanxiao, as a traditional food, has a long history in China. In the Song Dynasty, the custom of eating Yuanxiao was popular. At that time, it was called "Floating Yuanzi", and later generations became "Yuanxiao", also known as "Tangyuan". Peanut, sesame, sweet-scented osmanthus, red dates, nuts and other rich fillings, wrapped in glutinous rice flour, can be meat or vegetarian, with different flavors, and can be cooked, fried and other ways of eating, meaning reunion and happiness.

Yuanxiao was called "Tangyuan" at first, because it floated on the water after boiling, which was beautiful and reminiscent of a bright moon hanging in the clouds. There is a bright moon in the sky, dumplings in a bowl, and every household is round and round, symbolizing reunion and good luck. Therefore, eating Yuanxiao expresses people's love for family reunion.

In addition, the name of glutinous rice balls is similar to the pronunciation of "reunion", which means reunion, symbolizing the reunion of the whole family, harmony and happiness, and people also miss their parting relatives and place their good wishes for future life.
