Huo Jian Liu allowed its user to aim and launch rocket with greater accuracy. It also had greater range, less recoil, and significantly faster rate of fire than typical musket (due to the elimination of pouring powder charge, loading and ramming the ball down the barrel, and priming the flash pan steps in the reloading process). On top of that, the gun was cheaper to manufacture, as it did not need a strong barrel to withstand high chamber pressure, nor ramrod (although this was offset by its more costly rocket ammunition).

Regrettably, Zhao Shi Zhen's invention failed to catch the attention of Ming government, and never went beyond prototype stage.
