Tiān Jiù (天厩, Celestial Stable) is a Chinese asterism belonging to the Bì (壁, Wall) or Dongbi (東壁, Eastern Wall) lunar mansion. Among the Three Schools, it is classified as an asterism of the Wu Xian School (巫咸氏). The asterism consists of ten stars located to the north of Dongbi and near [[Wangliang|Wang Liang (王良)]], spanning the modern constellation [[Andromeda]] and [[Cassiopeia]].

== Concordance, Etymology, History ==

''Shuowen Jiezi'' (説文解字) defines the character ''jiù'' (厩) as "a stable for horses". The ''Shi Ming'' (釋名) elaborates: “''Jiù'' means to gather; it is where cattle and horses are gathered.” Tianjiu thus represents the celestial horse stable — the heavenly counterpart to the imperial post-horse stations and cavalry stables on earth.

The asterism's position near [[Wangliang]] is significant: Wangliang is the legendary charioteer, and his asterism includes the [[Tiansi]] (Heavenly Quadriga) — the four horses that draw the chariot. Tianjiu, located nearby, is the stable that houses and provisions these celestial horses. The ''Wu Xian Zhan'' (巫咸占) records: "Tianjiu, ten stars, north of Dongbi, near Wangliang."

Its function is directly tied to the imperial postal relay system (驛傳). The ''Chunqiu Hecheng Tu'' (春秋合誠圖) states: "The office of Tianjiu governs the guest houses." (天廄官主傳舍) The ''Wu Xian Zan'' (巫咸讚, ''Wu Xian's Eulogy'') describes it vividly:
<blockquote>Tianjiu establishes the post stations, racing with the water-clock. (天廄置驛，逐漏馳騖)</blockquote>
This paints a picture of celestial post-horses galloping at the same speed as time itself. The ''Jin Shu·Tianwen Zhi'' (晉書·天文志, ''Book of Jin, Treatise on Astronomy'') records:
<blockquote>Ten stars north of Dongbi are called Tianjiu, the office governing horses; it is like the post stations of today, governing the transmission of orders and the establishment of relay stations, racing with the water-clock — meaning its speed is urgent and swift, competing with the sundial and water-clock. (東壁北十星曰天廄，主馬之官，若今驛亭也，主傳令置驛，逐漏馳騖，謂其行急疾，與晷漏競馳也。)</blockquote>

The Kaiyuan Zhanjing (開元占經) preserves the astrological interpretation that if the stars of Tianjiu deviate from their proper positions, there will be matters of ancestral admonition (廟戒之事), and the ruler will be troubled by horses; otherwise, horses will fall ill.
