老外同学们，can you guys pronounce this sound in chinese-啧啧 ？？ i am just a little bit curious cos i never saw any foreigners make sounds like this whether it's on tv or in real life。 啧啧might have pinyin as zeze，but actually it's a click language。 “　You may have already heard a click language – called !Kung – being spoken if you have seen the movie "The Gods Must Be Crazy".” here an example http://www.youtube.com/watch?v=l_O-y4CMGBE thx thanks，汉伦兄 clicking sound ,明白了 也就是說英語國家能够发这个音 waiting for more answers
