Observe the patterns.
Understand the change.

1. Image, number and principle

Mei Hua Yi Shu, often called Plum Blossom divination, is a traditional way of forming and interpreting a hexagram. It works with the eight trigrams and their relationships. Three ideas offer a useful introduction:

In the text's distinction between xiantian and houtian casting, one approach starts with numbers and forms a hexagram; the other starts with an observed image and then combines its trigram with direction and time. This is a difference in the order of forming the cast, rather than a fixed split between your inner life and the outside world.

2. Look at the relationship, not just the label

Ti (体, body) is the subject or standpoint of the question. Yong (用, use) is the matter or influence it interacts with. Start by naming those roles in your actual concern. Body does not always mean you personally, and use does not automatically mean another person.

For YiPhase's one-moving-line method, the trigram containing the moving line is use; the unchanged trigram is body. Lines are counted from the bottom. A moving line in positions 1–3 makes the lower trigram use; a line in positions 4–6 makes the upper trigram use.

The Five Phase mapping is Qian and Dui → Metal; Zhen and Xun → Wood; Kan → Water; Li → Fire; Kun and Gen → Earth. The direction of generating or restraining matters:

These traditional tendencies are considered alongside the intermediate and changed patterns, seasonal strength and the actual matter. “A strong body and weak use” is not a complete judgement on its own. Each phase can support or restrain another; no phase is inherently fortunate or unfortunate.

3. Separate the present, the inner process and the change

A nuclear pattern invites examination of the process beneath the surface; it cannot reveal a secret as a fact. A changed pattern offers a traditional perspective on development, not a guaranteed endpoint. Relate both to conditions you can identify.

When reviewing a reading, ask: what is happening now, which tension needs attention, and what could change if I continue or adjust? The moving line is a particular position in the cast. It should not be turned automatically into your age, a date or a measured stage of your life.

4. Why did the visitor need an axe?

In the book's “Neighbour knocking at night” account, a visitor asks to borrow an object. The cast points toward associations of Metal and Wood. Shao Yong's son suggests a hoe; Shao Yong suggests an axe. Both tools can fit those materials. The time of the visit helps distinguish them: an evening need for firewood makes the axe more plausible in the story.

推数又须明理。

Working with the numbers also requires understanding the circumstances.

A traditional account in Mei Hua Yi Shu, Volume 1. The English retelling and translation are YiPhase's own. It is presented as a teaching story, not independently verified history.

The lesson for a modern reader is practical: the same symbolic association can fit several possibilities. A question about timing, purpose or what has already happened helps distinguish them.

On YiPhase, optional background serves this purpose. You can describe the situation and the decision without giving names, birthdays or identifying details. The casting calculation forms the hexagram; AI connects the supplied structure with the facts you choose to share. More context can make the explanation more specific, without guaranteeing what will happen.

5. Practise observing before deciding

Choose one real concern. You can work through these prompts privately; this exercise has no form to submit. Distinguish an observed fact from a hope, a fear or an interpretation.

A useful reading leaves you with a clearer question and a checkable next step. You can learn the symbolic framework while also improving the way you examine everyday choices.

6. A plum blossom story, and a wider idea of observation

The book traditionally associated with the Northern Song thinker Shao Yong includes the “Observing plum blossoms” account: sparrows fight on a branch and fall, prompting a cast. It is the familiar naming story of Mei Hua Yi Shu. Attribution and the compilation history require care; we introduce the account as part of the transmitted tradition, rather than claiming every passage was written personally by Shao Yong.

Shao Yong's broader philosophy of observing things includes yi wu guan wu (以物观物), discussed in the Huangji Jingshi. As a modern learning exercise, it can invite us to notice how hopes and fears colour our view, and to examine the situation on its own terms. This everyday paraphrase does not exhaust the original philosophical idea.
