Five Elements 五行
Wǔ Xíng
Wood, Fire, Earth, Metal, Water — five phases of qi that generate each other in one cycle (wood feeds fire, fire makes earth…) and control each other in another (water controls fire…). Every stem and branch belongs to one element; all BaZi reasoning is element reasoning.
In the classics
The generation cycle (wood→fire→earth→metal→water) and control cycle (wood⊣earth, earth⊣water, water⊣fire, fire⊣metal, metal⊣wood) predate BaZi itself; every classical text assumes them as the grammar beneath all reasoning. 《滴天髓》 additionally ties each element to a classical virtue — wood to benevolence (仁), for example.
In a chart
Every judgment in BaZi is an element judgment wearing different clothes: the Ten Gods are element relations, strength is element support, the useful god is an element the chart lacks functionally. The two cycles are not "good" and "bad" — generation can smother (a fire drowned in wood-fuel it cannot burn) and control can ennoble (timber becomes furniture only when metal shapes it). Direction and dose decide everything.
Worked example
Water controls fire — but a single cup of water thrown on a bonfire vanishes as steam. Classical reasoning always asks how much and in season or out, never just which controls which.
Where beginners misread it
Scoring charts by counting elements ("three wood, zero water — unbalanced!"). Balance is functional, not numerical; a missing element harms only if the structure actually needs it.
Spotting the cycles is Stage-1 work; weighing direction and dose in a real chart is what a teacher trains you to do — that layer lives at Yixin Academy.
