Chinese artist Kong Ning poses in a costume symbolizing a butterfly, which is decorated with 365 masks on its wings to represent the number of days in a year, during her performance art at the Badaling section of the Great Wall on the outskirts of Beijing January 1, 2015. Kong, whose works include themes related to China's air pollution problem, named her new performance art “Hua Die” (transforming into a butterfly) and performed it on the first day of the new year as she hopes that China has clean air for this year.

“Capoeira is a Brazilian art form that combines elements of martial arts, sports, and music. It was created in Brazil mainly by descendants of African slaves with Brazilian native influences, probably beginning in the 16th century. It is known by quick and complex moves, using mainly power kicks and quick leg sweeps, with some ground and aerial acrobatics, knee strikes, take-downs, elbow strikes, punches and headbutts. The word capoeira comes from Tupi, referring to the areas of low vegetation in the Brazilian interior”. – Wikipedia
