Teacher Li Peiguo checks a ginkgo tree he planted at Muying teaching point under Panpo Hope Primary School in Xiagang Town of Tai'an City, east China's Shandong Province, Dec. 5, 2019. In 1984, Li Peiguo went back to his alma mater of Muying Primary School, which was later transformed to the current Muying teaching point, as a teacher after graduation from high school. For 35 years, Li has remained on his post at the school, seeing batches of students graduating and colleagues leaving. Now, there are only Li and three first graders at the teaching point, where Li shoulders the responsibility of teaching all subjects to the three students. "If necessary, I would like to devote all my life to the teaching work here," said Li. (Xinhua/Guo Xulei)
