Armed police carry 17-year-old student Yan Peng after he was rescued out of the ruins of a two-story building in the quake-stricken Beichuan County in southwest China's Sichuan Province, May 14, 2008. A strong quake measuring 7.8 on the Richter scale struck Sichuan at 2:28 p.m. on Monday. At that moment, Yan was swung out of classroom by strong shake, but he came back to the classroom, trying to save his trapped classmates. Unfortunately, Yan was buried in the ruins for over 40 hours. Thanks to hard searching and rescuing for several hours by armed police, he was finally saved. (Xinhua Photo)
