Dui, the trigram of lake 兌☱ · quality: joy
Images
Dui has one yin line above two yang lines, and its image is the lake or marsh. Its quality is joy: like a lake it refreshes all things and gladdens people. In the family it is the youngest daughter, in the body the mouth, among animals the sheep.

The image, quality, family member, body part, animal and Later Heaven direction all come from the Shuogua, the commentary on the trigrams. The Earlier Heaven direction and number come from the chart handed down by the Song scholar Shao Yong; the five phases are a Han-dynasty and later correlation that the Shuogua does not make.
The Shuogua
兌，正秋也，萬物之所說也，故曰說言乎兌。
Dui is mid-autumn, when all things rejoice. So it is said: joy is spoken in Dui.
This chapter gives the directions and seasons of the eight trigrams, later called the Later Heaven (King Wen) arrangement.
兌為澤，為少女，為巫，為口舌，為毀折，為附決。
Dui is the lake, the youngest daughter, the sorceress, mouth and tongue, breaking and snapping, falling away.
From chapter eleven of the Shuogua: the wider range of images for Dui, from nature and family to objects, which readers draw on when interpreting a hexagram.
