Students listen to Andrew's class at the Second Minzu Middle School in the Tibetan Autonomous Prefecture of Huangnan, northwest China's Qinghai Province, Dec. 17, 2013. The 29-year-old Andrew Frankel from America has always showed interests in Tibetan culture. In 2012, he left his hometown for Qinghai and became a teacher at school. Apart from teaching English classes, he established an English books corner and a movie club, creating better English-studying atmosphere for local students. "I love staying with my students," Andrew said as he found the two-year teaching experience was valuable to his life. (Xinhua/Li Shaopeng)
