Yes, after all, paying attention to etiquette before class is not only a respect for ballet class and ballet art, but also a respect for yourself. If you want to cultivate the elegant and restrained temperament of ballet, please pay attention to all aspects of your self-cultivation before entering the ballet class. For example, the Bayi Lei Demonstration Base of the Central Ballet began to cultivate children's pre-class etiquette from the time when students first entered school, so as to avoid hindering children's ballet art path for other reasons.
