Qiong Tong Bao Jian 穷通宝鉴
the seasonal specialist
What it is
The classical text with a single, powerful obsession: climate. Also known by its older name 栏江网, it circulated through practitioners' hands before Qing editors (Yu Chuntai's edition is the standard) gave it its modern form. Its method: take each of the ten Day Masters through each of the twelve months — 120 cases — and state what each combination needs: warmth against cold, water against dryness, which one or two stems turn the month from hostile to distinguished.
What's in it
The doctrine this site's glossary meets as Season Command and the tradition calls 调候 ("climate adjustment"): before asking whether a chart is strong, ask whether it is comfortable — a winter 甲 wood may be technically rooted and still frozen; nothing matters for it until fire appears. The book is close to a lookup table with a worldview, which is why practitioners keep it within arm's reach long after they've internalised the other three.
One famous idea
The pattern its 120 cases repeat: 冬木非火不发 — winter wood does not flourish without fire (stated across its winter-wood chapters). A rule of thumb every modern reading of a December chart still applies, whether the reader knows its source or not.
How to read it today
As the fourth text and the first reference: dip in by your own Day Master and month, and you will see your chart's climate stated with startling directness. Its terseness is its trap — the one-line prescriptions assume the structure work of the other texts has been done. Where the prescriptions conflict with structure logic, the weighing between them is — once again — where a lineage speaks: Yixin Academy teaches the reconciliation explicitly.

Whether a chart is climatically comfortable, not just structurally strong — a winter 甲 wood chart may be rooted and still frozen until fire appears. Qiong Tong Bao Jian is the classical text built entirely on this one factor, Day Master by Day Master, month by month.
Qiong Tong Bao Jian vs Lan Jiang Wang?
Same work, older name (栏江网) — it circulated under that title before Qing editors, most standardly Yu Chuntai's edition, gave it its modern form and name.
