Photo taken on Jan 10, 2019 shows Chen Wanrong (1st R) and his two students wearing shoes stained with mud in Zhida village of Liangkou township in Sanjiang Dong autonomous county, South China's Guangxi Zhuang autonomous region. 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.
