Introduction to Beishan Forest Park: Beishan was originally a sand and gravel factory that had been mined for many years and a Gobi desert beach, which is the main source of dust in the city. In order to improve the ecological environment, Hejing County planned and launched the Beishan Greening Project in 2013 to plant trees in the barren mountains. Today, the ecological forest and protective forest have spread their green branches. The ancient wasteland is now full of green and is becoming a veritable forest park.
