Hidden in the mountains of Guangnan County, southeast Yunnan's Wenshan Prefecture, the Luodisong Village was once isolated from the outside world. 

In 1986, Nong Jiagui became the first and only teacher of the primary school in the village. For 34 years, he has taught 110 students and helped them enter middle schools outside the village. 

Though the school now has only seven students from four grades, Nong has never forgot his mission and done his best to help them learn as much knowledge as they can. 

“I’ll keep on teaching as long as I stay physically healthy," he said.
