What does 兌 represent in the I Ching?

兌 is traditionally associated with 澤 and is read through the three-line structure encoded in 110.

Is 兌 used on its own or only inside hexagrams?

兌 can be studied on its own as one of the bagua, but in a reading it usually matters because it appears as the lower or upper half of a hexagram.

Because the eight trigrams are the smallest named patterns in the system. Learning them makes the larger set of hexagrams much easier to understand.

In short

Dui is open at the top and solid below. It often suggests exchange, openness, expression, and pleasure with structure beneath it.

兌 is written as ☱ and encoded as 110. Read from bottom to top, its lines are bottom yang, middle yang, top yin.

This matters because the I Ching is structural first. The character of 兌 begins with its exact line order, not just its later symbolic associations.

Dui is open at the top and solid below. It often suggests exchange, openness, expression, and pleasure with structure beneath it.

When 兌 appears as a lower or upper trigram, it changes how the full hexagram is read by contributing its own pressure, orientation, and rhythm.

A strong way to study 兌 is to learn its line pattern, its natural image (澤), and then notice where it appears inside hexagrams.

That approach keeps the trigram readable as structure, symbol, and part of a larger figure all at once.
