Dance formations are oval, rectangular, octagonal and zigzag. Dance can be divided into two forms: simple or complex. Simple ones include some sliding steps, and complicated ones include some plots, such as the female partner refusing the invitation of the male partner and the male partner kneeling in front of the female partner.
