Sanming TonghuiVol. 1, On the Nature and Fortune of the Sixty Jiazi (verdicts & remarks)
Xin Hai Metal is an actual vessel of bells and tripods, delighting in Wood, Fire, and Earth. True Lu Horse, Suspended Needle [Xuan Zhen]. The four Metals of Ren Shen, Gui You, Geng Xu, and Xin Hai possess robust qi and do not mind ghosts.
Wu Zi Fire does not fear its ghost; it is the Fire of Thunderbolt within Water, possessed by divine dragons—for when there is Water, thunder roars. Yet if it encounters Bing Wu or Ding Wei Heavenly Water, it has reservations, as there is a clash of forces.
Generally, when the stems and branches of one's natal pillar are damaged, it indicates defects in the six sense faculties and having a beginning without an end, such as Ding Si meeting Gui Hai, or Ren Zi meeting Wu Wu. The rest follow this pattern.
