Chimpanzees and their 'mom' at Jinan Zoo

Yang Ying kisses a young chimpanzee at Jinan Zoo in Jinan, capital of east China's Shandong Province, Nov. 20, 2012. Prior to becoming a chimpanzee keeper in 2010, Yang Ying had been taking care of snub-nosed monkeys for eight years. When the four chimpanzee cubs she is now attending were first introduced to Jinan Zoo, Yang spent five to six hours a day with them to help them adapt to the new environment. The chimpanzee keeper takes pride in her job despite the laborious workload. (Xinhua/Guo Xulei)
