2. According to textual research, the name of the Youth League has a history of 1000 years since the Tang Dynasty. In Tomb-Sweeping Day, almost all the youth leagues have been steamed. In ancient times, people made the Youth League mainly as a sacrifice. Although the Youth League has been circulated for thousands of years, its appearance has not changed, but now its function as a sacrifice has gradually faded, but it has become a seasonal snack. Now, green balls are made of wheat straw, wormwood juice, other green vegetable juice and glutinous rice flour, and then stuffed with bean paste. The function of Qing Tuan as a sacrifice is weakening day by day, and more people regard it as a spring outing snack.
