午未合

Wu–Wei (午未) is a Liuhe, or Six Harmony, pairing between two Earthly Branches. In a BaZi chart, locate 午 and 未 in the lower characters of the pillars, then compare their positions and the surrounding branches. Recognizing the pair is not the same as establishing transformation: the month branch, supporting elements and relationships elsewhere in the chart belong to that further interpretation.

Consider the chart for a woman born on 15 June 1990 at 14:30: 庚午 壬午 辛亥 乙未. Read from left to right as year, month, day and hour. The Day Master is 辛, Yin Metal, taken from the upper character of the day pillar 辛亥. The branch beneath it is 亥. Keeping those two characters distinct makes it easier to locate both the person’s reference element and the branch relationships.

午 appears in the year and month positions; 未 appears in the hour position. The year 午 and hour 未 therefore form a Wu–Wei pair across the chart, with the month and day pillars between them. The month 午 gives a second occurrence of the same branch. These positions matter: identifying the characters establishes the pairing, while their placement describes how the relationship sits within this particular chart.

The month branch is also 午, so Fire supplies the seasonal setting. Traditional interpretations that associate 午未 with Fire examine that setting alongside support elsewhere in the pillars. The distinction is between a recognized branch pair and a broader claim about elemental transformation. A Fire association also leaves a further question: how Fire relates to the Day Master. For 辛 Metal, the hidden 丁 Fire in 午 is Seven Killings, while hidden 己 Earth is Indirect Resource. Those are different relationships within the same branch.

Hidden stems make this comparison more precise. Each 午 contains 丁 and 己; 未 contains 己, 丁 and 乙. The two branches share 丁 Fire and 己 Earth, while 未 also contains 乙 Wood. Relative to 辛, that 乙 is Indirect Wealth. Thus the label “Wu–Wei Liuhe” describes a relationship between branches, while the Ten Gods describe each stem’s relationship to the Day Master. The hour pillar’s visible 乙 and its hidden 乙 both have that same Indirect Wealth relationship to 辛.

Other pairings remain part of the chart. The year 午 and day 亥 form a hidden combination, 午亥暗合. The day 亥 and hour 未 form an arching combination toward 卯, written 亥未拱卯. Their positions are adjacent, unlike the year–hour Wu–Wei pair. The repeated 午 in the year and month positions is traditionally classified as 午午自刑. These names identify different branch relationships; each retains its own participants and position in the four pillars.

The upper characters provide another useful distinction. 庚 in the year pillar and 乙 in the hour pillar form a Heavenly Stem combination. 午未, by contrast, belongs to the lower row of Earthly Branches. A reader can therefore trace two separate connections between the year and hour pillars: 庚–乙 above and 午–未 below. Keeping the rows separate prevents a stem combination from being mistaken for a branch relationship.

For an orderly reading, begin with the four pillar positions, identify the Day Master, and then trace each relationship through its actual characters. In this example, the central facts are the two 午 branches, the hour 未, the 午 month and the 辛 Day Master. Together they provide a concrete basis for studying Wu–Wei alongside the chart’s other combinations. The guide to reading a BaZi chart explains how to locate these same parts in the four-pillar layout.
