When I came to Yichun, I was always asking the locals in a silly question. Where is Xiaoxing'anling? Many local people have been stupid by my silly question! In fact, Xiaoxing'anling is the general name of the mountain north of the Songhua River, with more than 70,000 square kilometers, and the area of Yichun is less than 40,000 square kilometers. The whole Yichun is in the hinterland of Xiaoxing'anling. In other words, the forest farms in Yichun belong to Xiaoxing'anling.
