Yunlong County, located in the west of Yunnan Province, is the southernmost habitat for China's first-class protected animal, the Yunnan snub-nosed monkey. It is also home to China's first-class protected plant, Taxus Chinensis. The abundance of wildlife and wild plants attracts poachers. He Minghan, He Min's father, was a forest ranger in Yunlong Tianchi Natural Reserve, where all his family lived. His duty was to protect natural resources.
