Indonesia, which has the reputation of "the country of a thousand islands", also has ten thousand kinds of customs, and its dance vocabulary and style are as mysterious and diverse as magic. Among them, the dance features of Java, Sumatra, Bali and Aceh are more representative. The dance posture is mainly semi-squatting, which is divided into one-legged gravity center and two-legged semi-squatting state. Keep your upper body upright, with your head and line of sight forward and your eyes looking down slightly; Dance movements are based on the imitation of animal forms. In terms of dance style, Java dance is slow and delicate; Balinese dance and Java dance have many similarities in style, but Balinese dance is more diverse in form and slow and urgent in pace. In addition to the movements of wrists and fingers, dancers also use their eyes to convey their feelings. Sumatra Malay dance is famous for its enthusiasm and cheerfulness; The dances in Kalimantan and the remote areas in the east are rough and simple, with primitive religious colors, especially the dances of the indigenous people in West Irianson, which have a strong sense of rhythm and appeal.
