Heilongjiang hand cannon

The Heilongjiang hand cannon or hand-gun^[a] is a bronze hand cannon manufactured no later than 1288 and is the world's oldest confirmed surviving firearm. It weighs 3.55 kg (7.83 pounds) and is 34 centimeters (13.4 inches) long. The Heilongjiang hand cannon was excavated during the 1970s in Banlachengzi, a village in Acheng District, Heilongjiang province, China. It was found alongside other bronze artifacts made in the style of the Jurchen Jin Dynasty (12th–13th century). The hand cannon was probably used in battles fought nearby in Banlachengzi in 1287 and 1288. The History of Yuan states that a Jurchen commander by the name of Li Ting led a group of soldiers equipped with hand cannons into a military camp in 1288, as part of an anti-rebellion campaign for the Yuan dynasty. The cannon currently resides at the Heilongjiang Provincial Museum in Harbin, China.
