Zhen Shui Yin (Axle Water Earthworm)

Zhen Lodge is the final of the seven lunar mansions constituting the Vermilion Bird of the South and is associated with the Water element, its divine embodiment taking the form of an earthworm deity. ‘Zhen’ originally denotes the transverse beam at the rear of a chariot, and the four stars of this lodge align to evoke the shape of a chariot chassis—hence Zhen governs transportation and, traditionally, matters related to death and mourning. In Daoist cosmology, Zhen is venerated as Zhen Shui Yin, the Star Lord of Axle Water Earthworm. Classical star-lore holds that when the Zhen Lodge shines brightly, carriages and horses remain unharmed and roads stay open and secure. In popular practice, devotees worship Zhen Shui Yin to ensure safe journeys, protection for all forms of transport, and freedom from travel-related mishaps. With Zhen’s inclusion, the full complement of the Twenty-Eight Mansions encircles the heavens, collectively upholding the cyclical harmony of the four seasons.
