Ayigulzeli Turson, 11, from Xinjiang, plays a hand clapping game with a friend at Peking University on July 22, 2016. She translated a Uygur jingle into Mandarin and taught it to her playmates. A total of 217 left-behind children, 9 to 17 years old, from Heilongjiang and Shanxi provinces and Xinjiang region, were invited by the All-China Federation of Trade Unions to tour Beijing for a week, free. The parents of these children are migrant workers who've left their hometowns to earn money to support their families, so the youngsters end up with the moniker 'left-behind'children.[Photo by Zou Hong/chinadaily.com.cn]
