It is made up of three solid lines stacked one on top of the other, representing the image of water that overflows from a lake or a pond. The trigram is associated with the concept of joy, pleasure, and social interaction.

In traditional Chinese thought, lakes are considered as beautiful, peaceful places where people can come together to relax and have fun. They are also associated with harmony and balance, as they are a natural product of the union between water and earth. The image of the lake, therefore, is often used to represent the ideal state of social harmony and balance that people should strive for.

As a trigram, Dui has a number of associations and meanings. It is considered to be a yang, or masculine, trigram, and is associated with the west and the element of metal. In terms of its symbolism, Dui is often associated with the idea of communication and the exchange of ideas. This is because lakes are often places where people come together to talk, share stories, and enjoy each other’s company.

In Chinese medicine, the trigram Dui is associated with the lungs, which are said to be the organs that govern the flow of energy in the body. The lungs are also associated with the emotion of sadness, and are seen as being particularly susceptible to stress and tension.

In divination, the trigram Dui is often associated with the concept of joy and happiness. It is seen as a positive sign, indicating that good things are on the horizon and that the querent should look forward to a period of happiness and social interaction.

Overall, the trigram Dui represents the idea of coming together in joy and harmony. It encourages us to communicate with others and share our experiences, and to seek out the pleasure and beauty in life. When Dui appears in a reading, it is a sign that we should embrace these qualities and look for ways to bring more joy and happiness into our lives.
