Beijing Qingshen Shanshui Flower and Wood Co., Ltd. was established in 1997. It is a high-tech enterprise and also a research base of the "National Key Laboratory of Efficient Production of Forest Resources" at Beijing Forestry University. The company is honored to be included in the "Beijing Annals - Landscape Greening Annals" and recorded in the history of Beijing‘s landscape development.

The company‘s base is located 2 kilometers east of Xiaodian in Yang Town, Shunyi District, Beijing, with a total area of about 1200 acres, including more than 800 acres of agricultural land and more than 300 acres of forest land. Moreover, more than 500 acres of agricultural land have been designated as high standard farmland construction areas. Since the return of forests to farmland, the company has set the development goal of "promoting both agriculture and forestry, and persevering", and has carried out the construction of "agroforestry composite management and integration" to create more value on limited land.
