The Guan Dao, also known as the Guandao or Yanyuedao, is a traditional Chinese polearm weapon that shares similarities with both a spear and a poleaxe. It can be described as a type of polearm that features a large, heavy blade mounted on the end of a long shaft.

The Guan Dao typically consists of a long wooden shaft, often around 6 to 7 feet in length, with a single-edged blade attached at a right angle near the top. The blade can vary in shape but commonly resembles a broadsword or a dao with a curved edge. The overall design allows for a variety of striking and sweeping techniques.

While the Guan Dao's blade shape and weight distribution make it capable of delivering powerful cleaving strikes similar to a poleaxe, its long shaft and overall length also give it some similarities to a spear. The length of the weapon provides reach and allows for thrusting attacks as well.

The Guan Dao historically gained popularity and association with the legendary Chinese general Guan Yu, who was said to have wielded a similar weapon. Today, the Guan Dao is primarily used in martial arts demonstrations, traditional performances, and for ceremonial purposes.
