Bagua is a group of trigrams—composed of three lines, each either "broken" or "unbroken", which represent yin and yang, respectively. Each line having two possible states allows for a total of 23 = 8 trigrams, whose early enumeration and characterization in China has had an effect on the history of Chinese philosophy and cosmology.
