Two men compete in a labor game during the Singing Festival in Baozeng Village for the ethnic Dong group, Lejiang Town of Multinational Autonomous County of Longsheng in south China's Guangxi Zhuang Autonomous Region, Sept. 2, 2017. People tend to believe that the Dong ethnic group keeps its civilization passing on by singing the stories from generation to generation due to lack of written language. The festival featuring music play and daily labor competition is also an occasion to express their wish for a good harvest. (Xinhua/Huang Yongdan)
