天德 is derived from the Month Branch and denotes a quality of heavenly protection — useful in mitigating unfavorable stars. When 天德 is present in a chart whose Day Master is 甲 (Yang Wood, Towering Tree), the configuration carries a specific classical register described below.
Configuration
- Day Master: 甲 (Yang Wood, Towering Tree) — wood element, yang polarity
- Auxiliary star: 天德 (Heavenly Virtue, Tian De) — Auspicious category
Heavenly Virtue (天德) — the classical register
天德 is derived from the Month Branch and denotes a quality of heavenly protection — particularly useful in mitigating the negative effects of other unfavorable stars. Its influence is one of moral rectitude, charitable assistance, and relief from hardship.

Yang Wood Day Master read with Heavenly Virtue
The Yang Wood (甲, Towering Tree) Day Master is one of the 10 classical BaZi Day Masters — the heavenly stem of the day pillar that anchors the chart's reading.
As a classically auspicious shen sha, Heavenly Virtue reads as a supportive layer when present in a Yang Wood chart — reinforcing the Day Master’s natural register without consuming it.
How to recognise this configuration in a chart
The configuration 甲日主見天德 is recognised when (a) the chart’s day pillar heavenly stem is 甲, and (b) the 天德 auxiliary star derivation produces a hit on one of the chart’s pillars (year / month / day / hour). The derivation rules for each shen sha vary — some are computed from the year stem, others from the day stem, others from pillar combinations. The derivation is the chart-reading skill the consultation provides; this page describes what the configuration means when it is present, not how to identify it.
Why generic Yang Wood Heavenly Virtue interpretation fails
Even when the configuration is correctly identified, the reading depends on which pillar 天德 lands on (year / month / day / hour), the Ten Gods active on that pillar, the Day Master’s strength in season, the Useful God of the chart, and the current luck pillar. Two Yang Wood charts that both contain 天德 can read in opposite directions depending on these contextual factors. Master Sean Chan’s BaZi consultation reads the full chart context; this page provides the configuration’s baseline register only.
