Volunteer Li Yun (left) repeats the English word "monkey" to a kid in the bottom class in Shepherd's Field, an orphanage supported by an American foundation in Wuqing, North China's Tianjin municipality, Nov 20, 2015. It usually takes weeks for the kids to learn a couple of new words as most of them are mentally disabled. Huahua is the only girl among the seven kids in her class who can talk.
