20 1 1 year1month, Sun Ningsheng retired after standing on the podium for 3 1 year, but after retiring, he immediately went to Yunnan and Guizhou to teach. Many people think that his behavior is a whim, but Sun Ningsheng said that he had a plan and premeditated, and he was ready to teach 10 years. He said that he had the idea of teaching in these remote mountainous areas before 10, so he began to exercise in 200 1 0, and this habit persisted for 10, so he decided to teach in remote mountainous areas in Yunnan and Guizhou at the moment of retirement.
The area he went to was Ciying Middle School, where the conditions were relatively poor. When he arrived at the school, he found that there was no library in the school, so he paid for it himself and contacted local workers to build a library for the local school. Moreover, in order to build a library, he collected books everywhere. With his efforts, he raised more than 20,000 books and moved them from the railway station to the school again and again. A few months later, the school had its first library, which brought great reading pleasure to the children here.
Moreover, during the teaching period, in order not to increase the burden on the school, he rented a house to solve the problem of food and shelter. Moreover, on weekends, he always visits local students' homes on foot. There are no transportation facilities in the mountain village area, so he can only walk every time. The farthest place is to walk back and forth from school for 8 hours, but he didn't leave any students' families behind. He visited every student's family to find out their specific situation. He not only helped and supported them in their studies, but also supplemented them frequently in their lives, so that students could eat, drink and study healthily.
