Sachs pointed out: "Dance breaks the boundaries between body and spirit, between indulging in lust and restraining behavior, between social life and venting personal characteristics, between games, religions, wars and dramas, and between all higher civilizations. The ecstatic human body forgets everything for emotional conquest and becomes the receiver of superhuman strength in the soul; The soul frees the accelerated body from its own burden and produces pleasure and joy. People need to dance, because the love of life also forces the limbs to stop being lazy; People are eager to dance, because dancing can make people gain magic and bring them victory, health and joy in life; When people of the same tribe dance arm in arm, there is a mysterious bond that connects the whole tribe with individuals and allows them to dance to their heart's content-no' art' can contain such rich content. "

"Dance" can't be confined to the category of "art", it also nurtures "art" and makes itself "art".
