What are the ancient weapons in China?

In ancient China, there was a saying of "eighteen kinds of martial arts", which actually refers to eighteen kinds of weapons. As for which eighteen kinds are there, there have always been different opinions. Generally refers to bows, crossbows, guns, sticks, knives, swords, spears, shields, axes, cymbals, halberds, dragoons, whips, mallets, forks, palladium and daggers. Some of these eighteen weapons have been eliminated, such as Shu and Ge. Some have evolved, like a shotgun. In ancient times, it was a big axe, but now it has become a small weapon with a blade and a hook. Each hand can take one. Such as the meridian cymbals.
