The Five Elements
The Five Elements are not the four elements of the West with one added. Wu Xing is better read as Five Phases or Five Movements, five faces of a single turning, the way a year moves from the green push of spring through the blaze of summer, the ripe pause of late summer, the clean cut of autumn, and the still depth of winter, and then begins again. Everything the old cosmologists could count they sorted into these five: the seasons and the directions, the planets and the notes, the organs and the tastes and the feelings. The point was never to label the world but to read how it moves, what feeds what, and what keeps what in line.
Wood mù
The upward push of new growth, vision, ambition, the seedling cracking the seed. Wood wants to expand; unchecked it overreaches, rooted it builds.

Earth tǔ
The still center the other four turn around, nourishment, stability, the harvest ground. Earth holds and reconciles; stuck it stagnates, balanced it steadies all.

Metal jīn
The cut of autumn, clarity, structure, the blade and the coin. Metal refines and decides; rigid it grows brittle, tempered it gives true edges.

Water shuǐ

生 + 克 · the two cycles
How the wheel keeps itself
The phases were systematized in the Warring States period, most famously by Zou Yan (鄒衍, c. 305 to 240 BCE), who used the conquest cycle of the elements to explain the rise and fall of dynasties. An older list appears in the Hong Fan (洪範, the Great Plan) chapter of the Book of Documents, which names water, fire, wood, metal, and earth and gives each its nature and taste. Under the Han, scholars like Dong Zhongshu wove the phases into a single correspondence cosmology binding heaven, the state, and the body, and the medical classic Huangdi Neijing (黃帝內經) mapped them onto the organs, emotions, and seasons in the form still used in Chinese medicine today. Two cycles do the work: the generating cycle (sheng 生), where each phase mothers the next, and the controlling cycle (ke 克), where each keeps another from running away with itself. When control turns to abuse the texts name two disorders, overacting (cheng 乘), too much control, and insulting (wu 侮), control running backward.
Generating (生) · the green rim
Wood feeds Fire (wood is the fuel), Fire makes Earth (ash and warmth become soil), Earth bears Metal (ore is mined from the ground), Metal carries Water (mist gathers on cold metal, and the old texts say metal melts to a liquid), and Water nourishes Wood (rain raises the tree). Each phase is the parent of the next and the child of the one before, so the wheel never rests on any single spoke.
Controlling (克) · the inner star
Wood parts Earth (roots break the soil), Earth dams Water (the bank holds the flood), Water quenches Fire, Fire melts Metal, and Metal cuts Wood (the axe fells the tree). Where generating is the line of nourishing, controlling is the line of keeping-in-check, the restraint that keeps any one phase from swallowing the others. Balance is never stillness here, only good keeping.
When it goes wrong
When a controlling phase grows too strong it overacts (cheng 乘), bullying its charge into collapse, as a hard drought (excess Earth) cracks and chokes a stream. When a controlled phase grows too strong it insults (wu 侮), pushing back up the line, as a roaring fire scorches the very water meant to quench it. The healer and the diviner both read for which line has gone wrong, then feed the weak phase or drain the strong one until the wheel turns easy again.
