Practical application of ancient fencing in China

Before the Han Dynasty, sword was an essential weapon, whether it was a long sword or a short sword.

After the Han dynasty, the ring knife appeared. For a long time, it was both a knife and a sword.

After the Han Dynasty, the sword gradually became a decoration. Although there are certain skills, knives occupy the mainstream of the battle. The shape of the sword has also changed gradually, just like the sword we see today, which has many decorative functions. The sword in the Warring States period was very wide and long. So it's more lethal.
