The Birch Ridge is named after the many birch trees on the ridge. It is the highest peak in the Zhangbei area. Birch Ridge is a geographical division as well as a landscape division and a climate division. The south slope has a carpetlike meadow while the north slope has the shade of dense forests. The south slope has a mild summer and the north slope has a chilly winter. This creates a unique environment on the Birch Ridge, where the pastures are next to the forests, and the two sides of the mountain are warm and cold.
