Liang Zhengqun gives a lecture on safety during the summer vacation at the Primary School of Lexin Village in Sanquan Township of Nanchuan District, southwest China's Chongqing Municipality, June 21, 2019. Given student pool draining and school's restructuring, since 2017, all students have been moving to Mazui Primary School after they finished the second academic year. Liang Zhengqun, who started her teaching career in 2003, became the last teacher in charge of the first and second year's teaching of the school. In 2019, June 21 marks the last day of the existence of Primary School of Lexin Village, as all six students will resume education in Mazui Primary School after they come back from the summer vacation in fall.
