“Battle” is a series of documentary photography about San Francisco’s local hip-hop dancers. Photographs focused on the freedom performance of hip-hop dance and the excited sentiment of dancers. In my hometown, Beijing, China, hip-hop survives in an awkward position. Hip-hop art is experienced by Chinese young people, mostly as a recreational activity in small groups. Chinese parents prefer to push their children to engage in finical work, so youth tend to suppress their true interests. When I came to America, the birthplace of street hip-hop dance, the vitality and enthusiasm of the hip-hop dance infected me. I began to go to all kinds of hip-hop dance studios, club and dance battle. This activity uses dancers’ body movement to show enthusiastic, energetic and unrestrained sentiment and feeling. Hip-hop dance is a kind of language; each limbs movement and different facial expressions represent the excited, freedom, sentiment and meaning.
