Tianqian the Celestial Money
17♒45 to 22♒40
Ma Duanlin (1317)
The ten stars of Tian Qian (Heavenly Coin) [Celestial Money] are northwest of Bei Luo (North Star), governing the accumulation of money and silk. Divination: If they are bright, the treasury will be full; otherwise, it will be depleted. When Venus and Mars guard the area, war and banditry will break out. [2]
Song History (1346)
Tianqian (Celestial Money) consists of ten stars located northwest of Beiluo Shimen (North Gate of the Military Camp); they govern the accumulation of money and silk (wealth), particularly military and treasury reserves. If these stars are bright, it indicates a full treasury; if dim or dark, it signifies emptiness. If Venus or Mars remain in this position, banditry will arise. If a comet or bright guest star enters here, the treasury will be robbed. [3]
