 Moves such as the crouching low leg sweep and "up rocking" (standing combat moves) are influenced by choreographed kung fu fights.The dancers’ ability to improvise these moves led way to battles, which were dance competitions between two dancers or crews judged on their creativity, skills and musicality.In a documentary, Crazy Legs, a member of breakdancing group Rock Steady Crew, described the breakdancing battle being like an old kung fu movie, "where the one kung fu master says something along the lines of ‘hun your kung fu is good, but mine is better,’ then a fight erupts."
