Dao is the Chinese term for their braodsword which feature a single-edge wide blade. It belongs to the four major weapons of Chinese martial arts. It was introduced to China as a result of the Mongol invasions, the broadsword with its characteristic curved blade became the most widely used short weapon in military circles. Its popularity was such that it eclipsed the older straight sword (Jian) as the dominant military sidearm.

The broadsword is single-edged and heavy. The strength of the weapon means that cutting movements tend to be large, expansive and powerful. In appearance, using the broadsword is "like splitting a mountain".
