Volunteers make qingtuan (green sticky rice balls) in Gangzha Economic Development Zone, Nantong, East China’s Jiangsu province, on March 26. Qingtuan is a traditional Qingming snack for people living in the lower reaches of the Yangtze River region. It is also used as a sacrifice for ancestors on Qingming Festival, also known as Tomb-Sweeping Day, which falls on April 5 this year. [Photo/IC]
