What are the similarities and differences between China ballet and western ballet?

Western ballet is also divided into many schools, such as royal, French, Russian and so on. China was originally introduced from the Royal School of England, which has a comprehensive teaching system, but lacks flexibility in teaching and role-building. Now more popular are schools from Russia, which pay attention to skills and muscle ability. The shortcomings are the same as above, while most western countries pay more attention to performance and role-building. China likes variations, and top ballet often appears in the form of competitions. The west pays attention to choreography, and top ballet mostly appears in the form of ballet and works.
