Li Jianwen carries his schoolbag and parpares to leave for the Dayandong Primary School in Dayandong Village of Guzhai Mulao Autonomous Township in Liucheng County, south China's Guangxi Zhuang Autonomous Region, Sept. 4, 2017. The 9-year-old Li Jianwen has to climb two mountains alone and spend one hour and a half to walk to his school every day. The village where Li Jianwen is living only has about 100 households and over 360 villagers. Since the autumn semester of 2016, all students over the third grade have been transferred to the town, gradually leaving Li Jianwen alone at the Dayandong Primary School. The teacher Pan Shanji was once worried whether Li Jianwen could keep on going to school and it finally proves that the child not only sticks to it but also studies very hard. (Xinhua/Li Hanchi)
