Ứng dụng: 注疏·参同契
后蜀彭晓注，将《周易参同契》析为九十章并作义疏，是现存最早具名分章注本。以「参同」为修丹与易象天地造化相参；乾坤为鼎炉门户，坎离为药物匡郭，纳甲、卦气、朔望定火候。虽兼涉炉火外事，主旨通于金液还丹与内象，影响朱熹《考异》、陈显微、俞琰等后世注家，确立「万古丹经王」的章句解释传统。
⚡ Ứng dụng: 依九十章次序读契：以乾坤为炉鼎、坎离为药、月相卦气为火候，指导还丹修持。

The text proves, via chaptered exegesis, that the Zhouyi, Yellow-Lao, and furnace work are one isomorphic system: trigrams encode firing phases, so alchemical timing is not metaphor but the same mathematics as the Changes—通真義 means opening that shared code until practice and classic seal each other.
1) Map personal luck-pillar transitions onto hexagram-like phase language (advance/retreat of yin-yang) rather than only ten-god labels. 2) Schedule intense cultivation in phases analogous to 進陽火 / 退陰符 matching your chart's seasonal strength. 3) Use line-by-line study: one chapter → one week of embodied experiment → record, before next chapter. 4) When Metal and Water are useful, favor descent/condense phases; when Wood and Fire are useful, favor ascent/advance phases—Cantongqi logic as BaZi pacing.
More systematically commentarial than poetic Cantongqi recitations; more classical-Yi fused than Xishan anecdotal 會真. It differs from pure moral Yijing ethics by insisting the Changes are a firing manual.
