Youth League is a traditional snack that people in the south of the Yangtze River eat in Tomb-Sweeping Day. According to textual research, the name of the Youth League has a history of 1000 years since the Tang Dynasty. In ancient times, people made Qing Tuan, which was mainly used for sacrifice. The shape of the Youth League has remained unchanged for thousands of years, but now its function as a sacrifice has gradually disappeared, and it has become a seasonal snack.

The flavor of the green ball is made of wheat straw, wormwood juice, other green leafy vegetable juice and glutinous rice flour, and then made of bean paste. The function of group worship as a sacrifice is weakening day by day, and more people regard it as a spring outing snack.

Green ball is green as jade, tender and fragrant, fat but not fat, and it is a natural green healthy snack. After steaming, the soft skin is green, the bean paste stuffing is sweet but not greasy, and there is a faint aroma of wormwood, which is delicious.
