Based on action, hip-hop can be divided into two categories: hip-hop and break dancing. Break: Skillful street dance requires dancers to have high strength, flexibility and coordination, and it is a highly skilled sports dance. (Not suitable for beginners) Second Street Dance: Dancing Street Dance, which has many styles such as Popping, Locking, House, Jazz and Wave. They don't need higher skills such as breaking, but they need more coordination and sense of dance, as well as flexibility and control of their limbs. 1 Popping, commonly known as Robert (robot dance), uses the vibration of body joints or the tension and relaxation of muscles to make continuous tiny movements, just like robot movements; 2. Locking, in which all parts of the body (mainly hand rotation) move quickly, and then stop at a certain position accurately, as if suddenly locked, resulting in dazzling aesthetic feeling and sense of strength; 3 House, a relatively young dance, is very diverse. House music is based on disco music in the 1980s, with Latin and African music elements, and its rhythm is very free and relaxed. Similarly, house dance also has many elements of Latin dance and African indigenous dance, and incorporates many other dance movements, such as popping, locking and Jazz. But compared with other kinds of dances, House pays more attention to the movements of lower limbs. Jazz, this dance is very old. Old jazz came into being in Britain as early as the last two centuries, wearing a suit and dancing faster with crutches. Neo-jazz combines elements of pop music and modern dance, and its movements are relatively large and tidy. In addition, there is a girl jazz specially for girls, which has a great effect on losing weight for girls. 5 waves, commonly known as current dance and wave dance, are like waves to transfer movements from one side of the body to the other. In recent years, a new Rave style has been derived from wave, which is characterized by a lot of twisting movements in the G part. 6 freestyle hiphop is more important than performing music (commonly used pop music), and dancing is more free. There are many very distinctive movements that cannot be classified as dancing.
