Blond woman fluent in Chinese

I just saw in the BBC a live report from Beijing.  It was by a blond woman who speaks in English with British accent.  But the astonishing thing is she was interviewing people on the street asking them questions in Chinese!  And then she was translating for the cameras.  Unbelievable.  I wonder how much of her translation was accurate.  Did she make up any part of the answers when she repeated them in English?  Very impressive.
