What formation do twelve people in Beijiangmei Square Dance change to look good?

You can use the formation of "three, four, five" first, and pay attention to the jack bracket to ensure that everyone can be exposed. You have to change the formation several times in the middle, and you can row three rows of four people and two rows of six people. Pay attention to the time, and finally you can return to the formation of "three, four, five". The dance formation should not be too complicated, otherwise it will affect the appreciation of the whole dance.
