Pī jiàn (披箭) is the name of a class of broadhead arrows. Most pī jiàn were hunting arrows. Their wide heads did more damage to an unprotected target like an animal but had limited penetrative ability through protection worn by soldiers. Some special narrower pī jiàn were in use in the military as well, those were primarily used for close ranges where the arrow still hit with a lot of force.
Soldiers could choose how many regular war arrows and broadheads they could carry.
In the 18th century, the Qianlong emperor started to use alternative writing, pī jiàn (鈚箭), using the archaic character pī 鈚. The arrow appears as such in the Huangchao Liqi Tushi (皇朝禮器圖式), or "Illustrated Regulations on the Ceremonial Paraphernalia of the Dynasty".
In Manchu, the type of arrow is called niru.
