Gunpowder weapons in the Song dynasty included fire arrows, gunpowder lit flamethrowers, soft shell bombs, hard shell iron bombs, fire lances, and possibly early cannons known as "eruptors". The eruptors, such as the "multiple bullets magazine eruptors" (bǎi-zi lián zhū pào, 百子連珠炮), consisting of a tube of bronze or cast iron that was filled with about 100 lead balls, and the "flying-cloud thunderclap eruptor" (fēi yún pī-lì pào, 飛雲霹靂炮), were early cast-iron proto-cannons that did not include single shots that occluded the barrel (thus called "co-viative" weapons). The use of proto-cannon, and other gunpowder weapons, enabled the Song dynasty to ward off its generally militarily superior enemies—the Khitan led Liao, Tangut led Western Xia, and Jurchen led Jin—until its final collapse under the onslaught of the Mongol forces of Kublai Khan and his Yuan dynasty in the late 13th century.

Gunpowder weapons in the Song dynasty in the context of Firearm
A firearm is any type of gun that shoots projectiles using high explosive pressure generated from combustion (deflagration) of chemical propellant, most often black powder in antique firearms and smokeless powder in modern firearms. Small arms is a subset of light firearms that is designed to be readily carried and operated by an individual. The term "firearm" is however variably defined in both technically and legally in different countries (see legal definitions), and can be used colloquially (sometimes incorrectly) to refer to any type of guns.
The first firearms originated in 10th-century Song dynasty China (see gunpowder weapons in the Song dynasty), when bamboo tubes containing gunpowder and pellet projectiles were mounted on spears to make the portable fire lance, which was operable by a single person and was later used effectively as a shock weapon in the siege of De'an in 1132. In the 13th century, fire lance barrels were replaced with metal tubes and transformed into the metal-barreled hand cannon, and the technology gradually spread throughout Eurasia during the 14th century. Older firearms typically used black powder as a propellant, but modern firearms use smokeless powder or other explosive propellants. Most modern firearms (with the notable exception of smoothbore shotguns) have rifled barrels to impart a stabilizing spin to the bullet for improved external ballistics.
Gunpowder weapons in the Song dynasty in the context of Gunpowder artillery in the Middle Ages
Gunpowder artillery in the Middle Ages primarily consisted of the introduction of the cannon, large tubular firearms designed to fire a heavy projectile over a long distance. Guns, bombs, rockets and cannons were first invented in China during the Han and Song dynasties and then later spread to Europe and the Middle East during the period.
Although gunpowder was known in Europe during the High Middle Ages due to the usage of guns and explosives by the Mongols and the Chinese firearms experts employed by them as mercenaries during the Mongol conquests of Europe, it was not until the Late Middle Ages that European versions of cannons were widely developed. Their use was also first documented in the Middle East around this time. English cannons first appeared in 1327, and later saw more general use during the Hundred Years' War, when primitive cannons were employed at the Battle of Crécy in 1346. By the end of the 14th century, the use of cannons was also recorded as being used by the Swedes, Poles, Russians, Byzantines and Ottomans.
