Seven Branch relations 刑沖破害合會拱
The seven Branch relations are how BaZi sorts the ways Earthly Branches interact: combination and meeting are alliances, clash and punishment are collision and grinding, break and harm are small damage and hidden injury, and the arch summons an absent branch. Read more →
Combination 合
In BaZi, Combination is attraction, alliance, binding. Five Stem combinations: Jia-Ji, Yi-Geng, Bing-Xin, Ding-Ren, Wu-Gui. Tendency: closeness, alliance (good or bad depends on who gets combined away, and whether it transforms). Read more →
Meeting 會
In BaZi, Meeting is Directional Meeting (same-direction qi gathering). Four bureaus: Yin-Mao-Chen → East Wood, Si-Wu-Wei → South Fire, Shen-You-Xu → West Metal, Hai-Zi-Chou → North Water. Tendency: one element surges, rewriting the chart’s strength balance. Read more →
Arch 拱
In BaZi, Arch is empty-spirit distant combination, something from nothing. Two kinds: arch-combination (arching a bureau’s peak) and arch-embrace (arching a Noble / Prosperity star). Timing: it pays off the year a Luck Pillar or year “fills it in”. Read more →
Clash 沖
In BaZi, Clash is the six Branch clashes (head-on collision). Six pairs: Zi-Wu, Chou-Wei, Yin-Shen, Mao-You, Chen-Xu, Si-Hai. Tendency: turbulence, change, drive (not all bad). Read more →

Five Stem Combinations 天干五合
The Five Stem Combinations pair each yang stem with the yin stem five places on: Jia-Ji make Earth, Yi-Geng Metal, Bing-Xin Water, Ding-Ren Wood, Wu-Gui Fire. A pair truly transforms only when the month and the whole chart support it. Read more →
Four Stem Clashes 天干四沖
The Four Stem Clashes set stems of the same polarity whose elements control each other: Jia-Geng, Yi-Xin, Bing-Ren and Ding-Gui. Wu and Ji Earth sit in the center and do not clash. A clash reads as a pull between ideas or directions. Read more →
Fu Yin and Fan Yin 伏吟
Fu Yin is when a luck pillar or year repeats one of your natal pillars exactly, often read as the same lesson coming round again. Its opposite, Fan Yin, where stem controls stem and branch clashes branch, often reads as a reversal. Read more →
