This submachine gun has been developed by Chinese Chang Feng corporation for Compact Submachine Gun trials initiated by PLA (Chinese Army) in early 1990s. This weapon has been designed by the same people who previously designed the QSZ-92 pistol, which is now in use by PLA and PAP. This design (chambered for new Chinese 5.8x21 DAP-58 round) lost the military trials because of overly complicated design, and by now is offered to Chinese law enforcement agencies, chambered for 9x19mm DAP-92 (Chinese version of 9x19mm Luger/Parabellum) ammunition.

The Chang Feng submachine gun is blowback operated and uses telescoped bolt which wraps around the barrel in forward position. Receiver is made from polymer and is open at the top; two pistol grips are integral to receiver. Primary feed is from helical magazine made from translucent polymer; magazine is located at the top of the weapon and is similar in design to magazines of US Calico submachine guns. Early prototypes also had secondary feed option, in the form of the QSZ-92 pistol magazine that was inserted into the rear pistol grip; it is not known how gun was fed if both magazines were inserted simultaneously. Chang Feng submachine gun is fitted with open sights, and has a mounting point for red dot or night sight just behind the rear sight block. Barrel of the weapon is threaded to accept optional detachable silencer. Shoulder stock is of telescoped (retractable) type, and is made from polymer.
