Highlights: Tianyuewan Hot Spring is located in Tangchi in Yuexi County, in the hinterland of Dabie Mountain. According to the inscriptions from the Ming Dynasty, it can be called one of the four famous historical springs in China, comparable with historical famous springs such as Huaqing Pool in Xi'an. Because the Chinese Zen Buddhist Master Hui Ke's dojo is located in Yuexi County, the sacred spring blesses people's well-being, as people form the base of a nation's well-being. Therefore, Tianyuewan Spring was conceptualized based on this Zen tenet.
