Four Green Wood combines the number 4, the inherited Green name and the Wood phase. Sonoda’s Later Heaven diagram pairs it with Xun. The classical text associates Xun with wind, wood and entry. That vocabulary gives the cultural label an image distinct from Three’s thunder. It does not demonstrate that a person is naturally diplomatic, indecisive or skilled at persuasion.
This is a calendar label, not a score. Your selected side of the displayed Beginning of Spring boundary determines the effective season year; uncertainty retains both adjacent labels.
The image of Xun
Four Green Wood combines the number 4, the inherited Green name and the Wood phase. Sonoda’s Later Heaven diagram pairs it with Xun. The classical text associates Xun with wind, wood and entry. That vocabulary gives the cultural label an image distinct from Three’s thunder. It does not demonstrate that a person is naturally diplomatic, indecisive or skilled at persuasion.
Wind and thunder offer a useful contrast
Three and Four share the Wood phase but not their paired trigram. Zhen presents movement; Xun presents entry, with wind as a natural image. Reading the contrast is a way to understand the symbol map. It should not be turned into a claim that one birth group acts directly while another must influence people indirectly.
Cultural vocabulary is not a social obligation
Old lists of correspondences contain claims and social assumptions beyond the limited images used here. This guide does not adopt predictions about trade, appearance, relationships or fate. Entry can be read as a metaphor while a person remains free to decline an invitation, state a direct boundary or choose not to adapt to someone else’s preference.
A new example: a change that reaches one shared routine
Suppose a household wants to reduce missed deliveries. Trying a clearly labelled collection spot in one routine can reveal whether the idea reaches the people who need it. This is FermatMind’s modern analogy for entry and extension. Whether the change works depends on access and agreement, not on the household members’ stars.
An optional check on how an idea travels
Choose one low-stakes suggestion. Note who has heard it, what they understood and whether they agreed to try it. A direct question may be more useful than further subtle signals. The exercise does not require you to become more accommodating, and a failed trial does not confirm a fixed Four Green personality.
Sources and the separate year calculation
Source roles are separate: Sonoda’s 1934 Kaisei Hōi Meikan, printed page 19, supplies the Later Heaven diagram pairing; the classical Shuo Gua text and Kong Yingda commentary supply the inherited natural images. These are cultural records, not scientific validation. The annual calculation uses the adopted NAOJ boundary table and the stated year convention. It omits forecasts, directions and month/day/hour stars. All present-day examples above are original FermatMind writing.
For the Gregorian year 2023, the adopted table shows Beginning of Spring at 2023-02-04 11:43 in Japanese Standard Time, UTC+09:00. Clearly after that boundary uses season year 2023 and returns 4; clearly before it uses 2022 and returns 5. The rule is ((1927 − season year) mod 9 + 9) mod 9 + 1. Unknown time or timezone, or birth within the displayed boundary minute, keeps both labels. Do not treat a local calendar date alone as an exact instant.
