Constellation Tianchuan, the Celestial Boat
28♉42 to 12♊19
The nine stars of Tianchuan, north of Daling, in the middle of the river, are the celestial boat, signifying smooth passage and safe crossing. Shi Shen said, “If it is not in Hanzhong, the ferry and river will be impassable.”
If it is bright, the world will be at peace; if it is dim or there is migration, the world will suffer war and loss. If the moon invades it, all rivers will overflow, and ferry crossings will be impassable. If the five planets invade it, water will overflow, and people will migrate. If a comet invades it, there will be great floods. If a guest star invades it, there will be water and war. If a blue cloud enters, the emperor will be worried and cannot sail; if it is red, it signifies war and the use of ships; if it is yellow or white, the emperor will be happy. [2]
The nine stars of Tianchuan, located north of Daling, are in the middle of the river. Also called the Boat Star, it governs crossings and also floods and droughts. If not in the middle of the river, the river will be impassable, and floods will occur. If the four stars in the center are equally bright, the world will be at peace; otherwise, war and loss are likely. The same applies to migration. The appearance or disappearance of a comet indicates a great flood and war. [3]
