Huochong (simplified Chinese: 火铳; traditional Chinese: 火銃) is a Chinese name for firearms. In pre-modern China, the terms chong and pao were used interchangeably at times without clearly distinguishing between a gun and cannon. By the early Ming dynasty (1368–1644), it could refer to both cannons or hand cannons. The term chong has been applied to numerous types of firearm weapons in China, including the hand cannons (shou chong), bowl-mouth cannons (wankou chong), double edged gun (liangtou chong), and big 100-bullet gun (da chong baizi). The Koreans and Vietnamese (sung and phao) also used the same terms to describe early firearms.
The oldest confirmed huochong, also the earliest cannon with a date of production, is a bronze bowl-mouth gun (wankou chong) bearing an inscription dating it to 1298 (see Xanadu Gun).
