What does DAO mean in Unclassified?

Dao

Dao is a category of single-edge Chinese sword primarily used for slashing and chopping, often called a broadsword in English translation because some varieties have wide blades. In China, the dao is known as one of the four major weapons, along with the gun, qiang, and the jian (sword), and referred to as "The General of All Weapons". Dao is actually a generic word used to denote any member of a family of single-edged, broad-bladed cutting or slicing tools, but in common, everyday usage means knife. The weapon, also known as dan dao when just one is used, is thereby thought to be an adaptation of the kitchen knives common to Chinese cuisine. Dao also appears in the names of such polearms as the pudao and guan dao, due to the knife-like shape of their blades.
