The existence of a number of different languages, dialects, and religious traditions has meant that the Filipinos developed no single national culture. Over many centuries of Philippine history cultural development has been local in nature, enriched by influences from China, Malaysia, Europe, and the United States. Indigenous folk elements find expression in literature and music as well as other cultural forms. Traditional sports include arnis, a kind of fencing with wooden sticks, and sipa, a game much like volleyball, except that the players use their feet rather than their hands and arms. Such sports as cockfighting and boxing are very popular, and American influence is seen in the wide popularity of baseball and basketball
