Dayi Earth
One of the sixty Jiazi Nayin, paired with Wushen and Jiyou, belonging to the Earth element in the Five Phases.
Dayi Earth is one of the Nayin Five Phases within the sixty Jiazi cycle, corresponding to the Wushen and Jiyou years. Its imagery derives from the broad, level soil beside ancient post roads, symbolizing the capacity to bear traffic and connect all directions. In traditional Nayin Five Phases theory, this earth is considered stable and load-bearing, possessing qualities of connection and transmission. Historically, in date selection or destiny analysis involving this Nayin, associations were often made with migration, travel, or communication. This kind of image reflects the ancient practice of analogizing natural substances with human activities.
