Editor’s note: Foping county is deep in the Qinling Mountains in southern Shaanxi. It has lovely mountains, clear waters and gentle weather. With forests covering 91 percent of the area, it is known as “a gene bank of biological resources (生物资源基因库)”, “the land of giant pandas” and “the hometown of Chinese cornel (茱萸)”. This makes it a great place for students to take part in nature study activities.
