Chinese language

The Chinese tend to pronounce bs as ps which is where the word Pidgin, as in Pidgin English comes from: it derives from the word "business" via the intermediate mispronunciation "pidginess". This was brought home to me today when I was talking to a cab driver in Singapore. He told me that the Chinese word for "yes" is "sir" and "no" is "poosir", describing it thus, "The Chinese word for 'no' is 'poosir', just like 'bush', President Bush: we call him President Poosir!"
