Ancient weapon: What kind of weapon does a gun with two heads belong to? Is there any practical value?

In ancient storytelling, the generals who used double guns were mostly double guns with spear heads at both ends, such as Lu Wenlong's double guns in The Legend of Yue Fei and Ding Yanping's double guns in The Romance of Sui and Tang Dynasties. I have seen two guns on the stage.

It is estimated that there should actually be such weapons.

In the past, when performing Qigong "iron gun stabbing throat", two people used the same gun when facing each other.

It is estimated that this kind of weapon should be used more immediately, and it can be played immediately. If the infantry wants to use it, the length of the gun will be much shorter and the power will be much weakened.

The advantage of this gun is that it can use backhand power. Generally, the backhand is stronger than the forehand, and the speed will be faster. But it is not easy to practice skillfully.

However, in the past, many guns had an anzu, that is, an iron cone at the end of the gun. Usually used to stick a gun in the ground, sometimes as a whip to beat a horse, or as a spur to stab a horse. It is similar to another spear head in a battle.
