What is the most important foundation in traditional dance?

Rhythm is the inherent law and framework of dance, which determines the rhythm, strength and fluency of dance movements and is one of the core elements of dance artistic expression. Traditional dance often pays attention to the standardization and skill of movements, requiring dancers not only to have superb skills and beautiful posture when completing dance movements, but also to convey emotions and stories through rhythm and show the profound connotation of traditional culture.
