Is there a change of formation for the latest square dances in 2015

There are. Liu Rong Square Dance choreographed two dances with variable formation in February, "Red China" and "Lanterns on the 15th day of the first month".

Jasmine Square Dance has choreographed "Auspicious Year of the Sheep" 5-member and 8-member varied formation versions, "What's Your Cow?" 5-member formation changes, "Night Comes to Fragrance" 12-member varied formations, "I" 16-member varied formations, "Open Lanterns and Colorful Colors" + "Immediately Rich" 16-member skewers, and "Mudman Love Song" 16-member ...... ....... There are other dance teams as well, so I won't list them all here. You'll find them if you search carefully online. Usually the dances in the competition will have a change of formation.
