Chen Wanrong tutors his second-grade student Wu Yanjin at a teaching site in Zhida Village of Liangkou Township in Sanjiang Dong Autonomous County, south China's Guangxi Zhuang Autonomous Region, Jan. 10, 2019. Located in a remote mountain village, most students had moved out of Zhida Village to other places thanks to the relocation policies involved in poverty alleviation measures. Eight-year-old Wu Yanjin and 11-year-old Wu Shengli became the only two primary students in Zhida Village in September last year taught by Chen Wanrong, the only one faculty of Zhida teaching site.
