Young Chinese helping sticky rice balls make a comeback

Weeks before Tomb Sweeping Day, which fell on Tuesday, young people in Shanghai waited in line for hours to enjoy qingtuan, or sweet green rice balls.

The snack, which has been around for centuries, is a must-have offering for the ancestral rituals around this time in the Yangtze River Delta.

Yet before the growth of social media and e-commerce, the snack had started to be forgotten as young people moved far from home. Now, it is regaining its popularity.
