Betawi is derived from Batavia. This name also represents Jakartan’s indigenous society which is admixture from Nusantara’s people. Javanese, Sundanese, Malays, Balinese, Manggarais, Buginese, Portuguese, Arabs, Dutch, Chinese and Mardijkers are integral part of Betawian society. In this dance as I watched it more than a year ago, there is a highly Chinese influence particularly in the dancers’ costumes. I forget the dance’s name, but I just say Betawian dance. Enjoy it.
