Students have lunch at school in the help of Li Zhaoqiong, wife of Ye Shiping, in Xihe Town of Pingli County, northwest China's Shaanxi Province, March 26, 2018. Ye Shiping, 53 years old, decided to stay behind at the Renjiaya Primary School as a teacher with his wife as the number of students here decreased to only 15. The school, located in remote mountainous area, is 30 kilometers away from the county. With the reduce of population, Ye and his wife became the only two teachers left in the school. Taking good care of their students, the couple determined to devote their life into the career here to help more students walk out of their living place and take a look of the outside world.
