If ten people jump out of the door from both sides, five people each. Then the horizontal line (four people in front, four people in two rows behind), the big circle (ten people in a big circle), and the vertical column (five people in two rows), and at the end of the vertical column, both sides jump from the first person in front (after receiving the fifth person), or two columns and then silently retreat back to the original horizontal line shape. These formations are orderly but not chaotic. We also participated in the formation competition, and the formation compiled by professional teachers was very beautiful. We went straight to this dance. Our dance is Liu Rong Square Dance (Sacred Heart), which is very cheerful and has a strong sense of rhythm.
