Li Yongbing and his relatives mourn for his deceased wife in Fuxin Township, Mianzhu City, Sichuan Province, southwest China, on May 1, 2009. Li Yongbing, 28, is a teacher at a primary school at Qingping Village in Mianzhu City. His wife Wang Qin, who was also his colleague, died in the May 12 earthquake last year and left their little son Li Zihao behind. In the first few months after the disaster, Li Yongbing worked as a volunteer. When his former primary school resumed class in August 2008, he returned to his post. From September last year, he started to take and learn psychological guidance as a volunteer and later helped his students to recover from the pains caused by the earthquake. [Xinhua]
