The earliest application of firearms in China.

1. The gun is the beginning of the end of the cold weapon era. Generally speaking, China's cold weapon era ended after the Westernization in the late Qing Dynasty, because gunpowder was used in the army.

2。 Whether it is true or not, please look at the historical facts: in June, Zhang blasted the thick walls with gunpowder and captured Chongqing. In August, Chengdu defenders fought bravely. After three days of siege, Zhang ordered the soldiers to cut down the big trees outside the city, hollow out the trunk, fill it with gunpowder, put it in the fuse, and then sent people to secretly dig tunnels under the city wall at night. Just as the defenders of the Ming Dynasty cheered the retreat of Zhang's army, flames were blazing, the city walls collapsed and Chengdu was occupied.

It can be inferred.

3。 In ancient China, a tubular firearm that fired projectiles with gunpowder was called a spear, which was the predecessor of the gun. The earliest bronze cannon was discovered in Song and Liao Dynasties. In the Ming dynasty, the ancient philosophers rapid-fire gun was made of fine copper. The launch was deafening and all the blows were destroyed. At the beginning of the Qing Dynasty, the cannon reached its peak, with excellent copper, fine casting, regular shape and gorgeous decoration, which represented the highest level of imitation of western cannons since the Ming Dynasty.

The first book about gunpowder formula was written in the eighth and ninth centuries. It is said in the book that "saltpeter is mixed with sulfur and realgar, and it burns densely", and there will be a phenomenon of "burning up, burning hands and burning face, and burning houses". The secret here should be honey. Honey can be turned into charcoal when heated. Sulfur, saltpeter and carbon are mixed together, which is the formula of gunpowder.

At the end of the Tang Dynasty, gunpowder had been used in the military. In the first year of God's Blessing (904), Yang Xingmi's army laid siege to Zheng's army (leading troops to burn dragons and shamans, leading strong men to the city first, but the quilt was urgent). The (Fei Huo) here refers to (artillery) and (rocket). (artillery) is to make the powder into a ring, ignite the messenger wire and throw it out with a trebuchet; (Rocket) is to tie a pink ball under an arrow, light a messenger wire and shoot it with a bow. In the Song Dynasty, wars continued, which accelerated the development of gunpowder weapons. The Northern Wei government established gunpowder workshops, and successively produced gunpowder arrows, artillery and other weapons with strong explosive power (thunderbolt) and (thunderbolt). 1259, Nanwei built a gun with giant bamboo as the barrel and gunpowder inside. In the Yuan Dynasty, the bronze casting fire system appeared again, which was called (General Copper). These weapons are all driven by gunpowder explosion and have shown unprecedented power in the war. The picture below shows Nanwei musket and Wei Bei gunpowder arrow.
