歌诀说：痘疹在乾卦（西北方）部位发出，病情较轻；在坎卦（正北方）部位先出，必然凶险；在艮卦（东北方）发出一部分，占三分；在震卦（正东方）出现，预后良好令人欣喜；在离卦（正南方）和巽卦（东南方）发出九分，处境极其危险；在坤卦（西南方）发出属于逆症，实在令人惊恐；只有在兑卦（正西方）发出才是真正吉利，必须将八卦各部位的吉凶分辨清楚。

The verse states: When the smallpox lesions appear in the Qian sector (northwest), the condition is relatively mild; when they first appear in the Kan sector (due north), it is inevitably ominous; a partial appearance in the Gen sector (northeast) indicates three parts severity; an appearance in the Zhen sector (due east) is auspicious and causes joy; appearances in the Li sector (due south) and Xun sector (southeast) reaching nine parts indicate extreme danger; an appearance in the Kun sector (southwest) constitutes a counter-flow syndrome, truly alarming; only an appearance in the Dui sector (due west) is truly auspicious. One must clearly distinguish the fortune and misfortune among the eight trigrams.
