Latin dance is divided into international standard Latin dance and Latin dance. Latin dance was all the rage in the first half of the 20th century, but now it has only historical significance. Folk dances include salsa, mambo and merengue. Latin dance is the origin of international standard Latin dance. As a folk dance culture in America, Europe and Africa, it gradually merged, evolved and perfected on the American continent, and finally developed into today's international standard Latin dance.
