The launch center straddles both sides of the Ruo Shui river.

The Dongfeng site also includes People's Liberation Army Air Force (PLAAF) test flight facilities, a space museum and a so-called martyr's cemetery (东风烈士陵园).

Its facilities are state of the art and provide support to every phase of a satellite launch campaign.
