Taiwanese culture is influenced by Chinese traditions. When greeting others, many Taiwanese will look down in a sign of respect while westerners tend to smile. Names follow traditional Chinese conventions with surnames first and sometimes poetic personal names. In introductions, use an academic or professional title with the surname. Taiwanese cuisine blends influences from central and southern Chinese provinces and includes dishes like grass jelly with mango and tortilla chile oyster sauce. Music and dance styles reflect Taiwan's aboriginal, Chinese and western influences and include genres like folk songs, cheguzhen burlesque singing and the Twelve Parade Grannies dance.
