They get together, dance, entertain themselves, and sometimes even dance for fun, forming different styles and genres. Representative dances are Brelin Dance and Lock Flow (Wave). These dances are mainly improvisation, and some are accompanied by hip-hop movements such as backspin and head spin, which change with the passage of time and the development of music. The appearance of hip-hop music school has given hip-hop a brand-new interpretation. With the performances of pop stars and their MTV works, this "cool" wind has spread all over the world.

At present, with the popularity of HIP-HOP, hip-hop not only occupies a place in the pop music scene, but also has become a very fashionable fitness way in China.
