name for the generic
Chinese broadsword,(there are many kinds of daos, i.e kwan dao, dadao,and pudao)which is one of the most powerful of all kung
fu weapons.

Monkey) because of its versatility- it can be effective at long,
mid, or short range, and some forms involve use of two daos. It is considered one of the four
basic weapons,along with the staff,spear, and straightsword, and has earned the name "The Marshal of all Weapons."
