Saihanba is located in Weichang Manchu and Mongolian Autonomous County, Chengde City, Hebei Province. Historically, the Saihanba area was once degraded into a barren mountain on the plateau. "Birds have no trees, and yellow sand covers the sky." After the founding of New China, Saihanba began to establish a state-owned forest farm to be responsible for afforestation in barren hills and wasteland. After three generations of Saihanba people's efforts in afforestation, Saihanba has become a vast forest today.
