Tianshi refers to a city located in China. While specific geographical details are limited in general records, it is associated with historical and cultural contexts within the region.
The name is also linked to the Way of the Celestial Masters, a Chinese Taoist movement founded by Zhang Daoling in 142 AD. This religious movement gained significant influence after its followers rebelled against the Han dynasty and won their independence in 194. At its peak, the sect established and controlled a theocratic state situated in the area that is now known as Sichuan.
