Dagang Machinery Forest Farm, Zhenlai County, Jilin Province, is located in the northwest of Zhenlai County and on the Dilonggang. Soil carbonated chestnut soil (commonly known as white dry soil) was planted in the field in the spring of 1964. Ten perennial seedlings of Pinus sylvestris were planted on white dry soil in the hospital. After more than two decades of natural growth, it is now in good condition and its color is normal.
