Choosing a focus line: yong shen and the Five Relationships

Five categories behind the traditional name

The traditional term Six Relatives is commonly used even though the element relationship table contains five categories. Each line receives a branch, the branch has an element, and that element is compared with the element of the hexagram’s palace.

An element that generates the palace element is Parent. One generated by it is Child. An element that controls it is Officer/Ghost. An element it controls is Wealth/Spouse. The same element is Sibling. The words are symbolic roles, not proof that a literal parent, child or ghost is involved.

For a Metal palace, Earth is Parent, Water Child, Fire Officer, Wood Wealth and Metal Sibling. The reference matrix below shows every palace-element and line-element pairing from the engine.

Match the question before interpreting the line

The site’s question categories associate Career with Officer, Money with Wealth, and Health with Child. Decision and Other use the Self line. These are the product’s declared category conventions; a nuanced traditional consultation can distinguish more specific subjects.

In traditional practice, exams and documents are associated with Parent. The current form has no separate exam or document category: choosing Other uses the Self line, not Parent. Keep that difference in view before interpreting an exam question.

Relationship questions inherit the traditional male-Wealth and female-Officer convention. That reflects the historical wife/husband framework. It should be understood as the chosen subject role, not as a claim that every contemporary relationship fits that framework. State who and what the question concerns so the reading can keep the roles clear.

The table below is generated from the same category selector used by the tool. It does not silently invent a different rule for the English interface.

When the focus is absent

Some hexagrams do not contain all five relationship categories among their six visible lines. That is an ordinary structural property, not an invalid cast or a reason to keep casting until a preferred symbol appears.

Traditional methods can locate a hidden spirit (fu shen) in the palace’s primary hexagram. MingLiMR does not calculate hidden spirits. It states which category is missing and makes any interpretation from the available Self/Other axis, moving lines and context, with that limitation explicit.

The hexagram library shows the missing categories for each published entry. It never inserts an imaginary line to make a question look fully supported.

When the category appears twice

A duplicate category requires interpretation rather than a blind “take the first row” rule. Traditional considerations include movement, seasonal support, contact with Self or Other, and the month and day. The reading should identify which line it is discussing and why.

The focus line and Self line can coincide, but they answer different questions. The focus describes the subject; Self describes the questioner’s position. Their relationship is part of the reading.

Calculation and interpretation have different boundaries

The engine establishes the branches, elements, relationships and Self/Other positions. Evaluating the focus against month and day influences, weighing movement, or proposing timing belongs to interpretation. A line’s appearance in a computed table does not mean its real-world outcome has been mechanically proven.

For health questions, these symbols cannot diagnose a condition or establish treatment. For money or career questions, use them as a reflective framework alongside actual evidence and circumstances.

Do not confuse this with BaZi’s Useful God

BaZi uses the same phrase for an element or structural role selected under a balancing or other interpretive method. Six-line I Ching uses it for the question’s subject within a cast. Read the BaZi favorable-elements guide if you encountered the term in a birth chart.
