Yin-Mao-Chen Three Meeting of Wood

Yin, Mao, and Chen are consecutive Earthly Branches corresponding to early, middle, and late spring. Together they cover the full spring season, whose dominant direction and Element are associated with the east and Wood. In modern BaZi terminology, the complete set is called the Yin-Mao-Chen Three Meeting of Wood.

A Three Meeting is based on a continuous seasonal and directional grouping, not on all three branches having the same basic Element. Yin and Mao are Wood branches, while Chen is an Earth branch, yet Chen still belongs to the late-spring part of the eastern group.

Chen joining the Wood Meeting does not mean its basic Element simply changes from Earth to Wood. Yu Ding Xing Li Kao Yuan places Chen within the spring sequence of Yin-Mao-Chen while separately classifying Chen, Xu, Chou, and Wei as Earth branches. Seasonal position and a branch's basic Element are therefore two different layers.

San Ming Tong Hui also identifies Chen as the storage of Water, while Wei is the storage of Wood. The Yin-Mao-Chen Wood Meeting is therefore based on the eastern spring season, not on Chen being a Wood storage branch.

Both structures strengthen Wood, but they are formed differently. Yin-Mao-Chen uses three consecutive branches covering the eastern spring season. Hai-Mao-Wei is a Three Combination based on the growth, peak, and storage stages of Wood.

The two should therefore not be treated as the same structure simply because both point toward Wood.

Once all three branches are present, the main question is what stronger Wood does to the chart. If Wood is useful, the meeting can reinforce it. If Wood is already excessive, the same structure can push the chart further toward Wood.

The concrete life area still depends on the Ten Gods represented by Wood and on the pillar positions of Yin, Mao, and Chen. Other Combinations, Clashes, Punishments, Harms, and Breaks must also be considered.
