What is the name of Nezha's spear?

Nezha’s spear is called the Fire-tipped Spear.

The weapon, known in Chinese as the huǒjiān qiāng, is one of Nezha’s best-known magical arms in the popular tradition surrounding Investiture of the Gods. Nezha is commonly depicted holding it in battle, often alongside the Wind Fire Wheels, the Universe Ring, and the Red Armillary Sash.

These objects are separate weapons or magical treasures, which makes this question easy to confuse. The Wind Fire Wheels provide supernatural mobility, the Universe Ring is a powerful throwing weapon, and the Red Armillary Sash can restrain opponents. The Fire-tipped Spear is the polearm among the group.

There is also a literary distinction worth knowing. Nezha appears in both Investiture of the Gods and Journey to the West, but the two portrayals are not identical. In the original Journey to the West, he is described with a different set of six weapons and does not use the familiar Fire-tipped Spear, Wind Fire Wheels, or Universe Ring in the same way. Modern art and television adaptations often blend these traditions.
