	~~In [[Chinese astronomy]] the star~~ is known as the star of the 'celestial wolf' ({{CJKV\|t=天狼\|s=天狼\|j=天狼\|}}; [[Pinyin\|Chinese romanization]]: Tiānláng; [[Romanization of Japanese\|Japanese romanization]]: Tenrō~~;<ref>{{harvard citation\|Holberg\|2007\|loc=p~~. ~~22}}</ref>~~ in the [[wikipedia:Well (Chinese constellation)\|Mansion of Jǐng]] (井宿).Several cultures also associated the star with a bow and arrows. The Ancient Chinese visualized a large bow and arrow across the southern sky, formed by the constellations of [[Puppis]] and Canis Major. In this, the arrow tip is pointed at the wolf Sirius.
