Sanming TonghuiVol. 1, On the Nature and Fortune of the Sixty Jiazi (verdicts & remarks)
Bing Xu Earth is mounds and hillocks; it delights in spring, summer, and Water. Heavenly Virtue, Canopy, Flat Head, Deaf and Mute. Ding Chou is Water of gathered blessings.
It most cherishes being engendered by Metal, and dreads Xin Wei, Bing Chen, and Bing Xu, which bring Punishment and breaking.
The Essential Discourse on the Five Elements says: "Ding Chou and Yi You, in their energetic numbers, are dispersed and frail Water, where Yin flourishes and Yang is weak.
Those endowed with them possess clear, discerning capacity—rich in wisdom yet scarce in blessings; but if sustained by the flourishing qi of Water and Wood, Yin and Yang harmonize, forming a presence of lofty nobility and prominence."
