鼎Ding.The Cauldron.
Fire rises above Wind and Wood: fuel enters flame and raw material becomes nourishment. Ding concerns cultural transformation, the vessel that holds change and the refinement of people, knowledge and resources into sustaining value.
Build the vessel that can refine what change has released.
Ding is the ritual Cauldron: a practical instrument, cultural symbol and container for transforming ingredients into shared nourishment.
Change alone does not create civilisation. Renewal becomes durable when capable people, right positions and a sound institutional vessel convert potential into value.
Fire above. Wind and Wood below.
Wood feeds Fire. The lower trigram supplies penetration and fuel; the upper brings illumination and transformation.
The right vessel turns resources into culture and capability.
The governing proposition
鼎：元吉，亨。
The Cauldron. Supreme good fortune. Success.
Wood enters Fire
鼎，象也。以木巽火，亨飪也。聖人亨以享上帝，而大亨以養聖賢。
The Cauldron is an image. Wood enters Fire, producing cooking. The sages prepared offerings and nourished the worthy and capable.
Correct position and stabilise the mandate
木上有火，鼎；君子以正位凝命。
Fire above Wood: the Cauldron. The cultivated person corrects positions and consolidates the mandate.

Design the vessel before demanding transformation from its contents.
Work and leadership
Align roles, capacity and governance so talent can be refined and served rather than spilled.
Relationships
A relationship transforms people only when its container is stable, its boundaries usable and its nourishment shared.
Timing and decisions
After major change, invest in institutions, rituals and skilled people that can hold the new order.
Ding is constructive when the vessel can safely transform and distribute what it contains.
