Topping yin (1 yin at top)
Symbolism
The character 兌 (duì) means exchange, joy, contentment. The trigram has a yin line at the top, two yang below: inner strength supports outer suppleness. It is the lake that reflects the sky, whose surface welcomes everything — rain, light, the thrown stone — without breaking.
The sheep is its animal — gentleness, social attachment, the warmth of the flock. Lake and sheep share the same quality: they make things peaceful.
General meaning
Duì designates the joy that circulates. Not solitary ecstasy, but shared contentment that fluidifies relations. It is the smile, the kind word, the banquet, friendship.
Received in a reading, Duì invites letting oneself be carried by what makes the situation more joyful for everyone. Joy is not a whim; it is a policy of fluidity.
As upper trigram
When the Lake is above, the general mood is light, sociable: a context that welcomes, that laughs, that shares. Take care not to confuse this lightness with superficiality.
As lower trigram
When the Lake is below, the subject is in active joy. Something that circulates, that shares, that rejoices.

Frequently asked
- Is Duì always positive?
- Largely yes, but the Yi Jing stays vigilant. Pure joy can become flattery, complacency, words that please but lie. The classic commentary warns against "joy that penetrates" — the kind that seduces without nourishing.
- What link between Duì and speech?
- Very close. Duì is traditionally associated with the mouth, with eloquence, with discourse. Joy circulates through words. The card invites speaking — but speaking well, with sincerity, without cynicism. Right speech is shared joy.
