Bixiu (毕宿), or Bi (毕), one of the Twenty-Eight Mansions, is the fifth mansion of the White Tiger of the West. It represents a long-handled hunting tool with a small mesh, used for catching hares or birds. It corresponds to eight stars in the constellation Taurus.

== Concordance, Etymology, History==

The shape of Bi was envisioned by ancient Chinese as a hare-catching net with a small mesh and a long handle. In astrology, it is used to govern matters like hunting rabbits or warfare in border regions.

Bi and its surrounding celestial region were viewed as a battlefield on the frontier, with the Mao (昴, Pleiades) as the opposing force, and the border lying at the Tianjie (天街). Bi itself is seen as a war chariot, used for hunting or warfare. Its brightest star, α Tau, is regarded as the Border General. Next to it is a star named Fuer (附耳, σ2 Tau), meaning "whispering close to the ear" or secret plotting.
