In addition to fireballs and rockets, the world's earliest tubular firearms also appeared in the Southern Song Dynasty. In the second year of Shaoxing, Song Gaozong (A.D. 1 132), Dean County magistrate invented the first tubular firearm. This kind of firearm now looks very crude, that is, putting gunpowder into a rough bamboo pole, igniting the tail in battle and burning the enemy with the sprayed flame. It is operated by two or three people. Although the style of this weapon is simple, stereotyped writing defeated a skirmisher led by a man named Hengli, and stereotyped writing became the originator of modern tubular firearms, and this small-scale operation also officially put tubular firearms on the historical stage.
