The five movements (五运) — Wood, Fire, Earth, Metal, and Water — each govern a year and carry a distinct set of climatic and physiological tendencies that classical wellness theory uses to guide year-by-year lifestyle adjustments. Knowing which movement governs the current year tells you the broad climatic backdrop against which all the finer details — six qi, solar terms, guest-host overlays — unfold.
Season and climate correspondences for each movement
Each movement corresponds to a season and a climatic quality. Wood (木) corresponds to spring and wind, bringing a climate of growth, expansion, and upward movement. Fire (火) corresponds to summer and heat, bringing intensity, activity, and outward expression. Earth (土) corresponds to late summer and dampness, bringing stability, nourishment, and centrality. Metal (金) corresponds to autumn and dryness, bringing contraction, clarity, and inward gathering. Water (水) corresponds to winter and cold, bringing storage, stillness, and conservation. 《素问·五运行大论》 lays out these correspondences, connecting each movement to its season, climate, and associated natural phenomena.
Sufficient, deficient, and balanced states
《素问·五常政大论》 takes this further by classifying each movement into three states: sufficient (太过), deficient (不及), and balanced (平气). A sufficient Wood year brings abundant wind and vigorous growth; a deficient Wood year brings muted wind and weakened vegetative energy. A balanced year sits between the two extremes. The classical text describes how each state affects the natural world — the winds, the rains, the crops, and the animals — and by extension, how the prevailing climate might influence human wellness patterns.
How TianJi identifies the yearly movement
TianJi identifies the governing movement for any given year by mapping the year's heavenly stem to its corresponding element, then determining whether the stem's yin-yang polarity makes the movement sufficient or deficient. This yearly movement becomes the foundation layer of every TianJi report: the daily card, the birth-year snapshot, and the half-year view all build on top of it. Each movement label carries a citation to the relevant Suwen passage, so you can trace the correspondence back to its classical source.
Climatic tendencies, not deterministic outcomes
The five movements describe climatic tendencies, not deterministic health outcomes. A Metal year does not mean everyone will experience dryness-related problems; it means the environment carries a dry, contracting quality that classical guidance suggests harmonising with through diet and lifestyle. The movements are a framework for living in rhythm with the year's character — educational and preventive, not predictive or diagnostic.
