Pupils wearing traditional costumes read classic poetry in an event to learn Duanwu customs at Cuitingyuan Elementary School in Hefei, capital of east China's Anhui Province, June 16, 2015. Duanwu Festival, also known as Dragon Boat Festival, is to commemorate Qu Yuan, a patriotic poet and minister of the ancient state of Chu during the Warring States Period (475B.C.-221B.C.) in the Chinese history, who drowned himself before his state fell to the invasion of the enemy. Duanwu Festival will fall on June 20 this year. (Xinhua/Du Yu)
