The bagua(eight trigrams )represents the fundamental principles of reality, seen as a range of eight interrelated concepts. Each consists of three lines, each line either "broken" or "unbroken," respectively representing yin or yang.

Bagua represents the early Chinese philosophy, it also has an impact on traditional Chinese medicine, martial arts, music and mathematics.
