After a three-year hiatus, dancers from France, the U.S., Republic of Korea, Japan, and China grooved their way back to east China's Hangzhou, seeing a boom in street dance cultural exchanges among enthusiasts. They reunited for the "Crazy Dancing Competition" that coincided with International Dance Day, which is celebrated on April 29. The dancers squared off in intense battles, while bringing with them the core principles of street dance culture, peace, love, unity and having fun.
