China Dance:
The body rhyme training of China Dance fully embodies the distinctive national characteristics of our Chinese nation. On the basis of basic training, it draws lessons from the training system of ballet and combines the techniques of hand, eye, body and step of Chinese opera and martial arts, which still has unique national characteristics, and its performance is very different from other dances.
China's classical dance is rich in dance, and its basic movements are very sculptural. It is not only an expressive dance action, but also makes the skills of jumping, rotating and turning over have a strong sense of sculpture. Basic dance requires high coordination of legs, trunk, arms, head and eyes. Therefore, basic dance training is actually a means to master the style of classical dance.
