These bows are based on strength bows of the imperial martial examination in the Qing dynasty. The participants of these examinations were required to draw these bows to a full draw as a part of proof of their strength and technique. (The other tested subjects were archery on foot, archery on horse, and weighting lifting).
These strength bows are not designed to shoot arrows efficiently in particular. However, it can be shot, given that sufficiently heavy (at least 16GPP) and stiff arrows are used. For safety, DO NOT shoot light and soft arrows using this bow.
