The green dumplings are the most representative food of the Qingming Festival, which are green and oily, soft and sticky, not too sweet and not too greasy, with a light but long grass aroma, and are even more fragrant and smooth in the mouth. The custom, which dates back more than 2,000 years, is that people prepare a lot of pastries in advance to fill their stomachs because they can't make fires on the Cold Food Festival.

The green dumplings were made by pounding green wormwood and glutinous rice flour and then stuffing them with bean paste, and could be kept for 3 to 5 days, thus meeting the needs of people for rituals and eating without cooking. The development of green dumplings has been to the present day, as the function of rituals is increasingly diluted, more is to bring people the experience of tasting fresh food.
