Sanming TonghuiVol. 1, On the Nature and Fortune of the Sixty Jiazi (verdicts & remarks)
Jia Xu Fire is the resting place of Fire, favoring spring and summer. Associated with Proper Seal, Canopy, Flat Head, Suspended Needle, Broken Character, and Cudgel. Jia Xu is Fire of self-storage. It does not disfavor abundant waters, only dreading Ren Xu.
As the saying goes, 'being overcome within the tomb, its calamity is inescapable.' The Summary of the Five Elements says: 'Jia Xu Fire acts as both Seal and Storage, harboring the qi of extreme Yang concealed within.
Encountered in noble structures, wealth and honor expand gloriously. It only dreads repeated birth, guarding against misfortune lurking within good fortune.' Yi Hai is Hidden Bright Fire.
Its qi is smothered and unexpressed; it relies on Ji Hai, Xin Mao, Ji Si, and Ren Wu to burst forth, and when Wood born of Wei generates it, spirit and vigor flourish. Having the Water of Gui Hai or Bing Wu is inauspicious.
