A said that Professor Wang was not from Suzhou, but from Shanghai. B said that Professor Wang was not from Shanghai, but from Suzhou. C said that Professor Wang was neither from Shanghai nor from Hangzhou. After listening to the above three people's judgments, Professor Wang said that one of them was all right, and one of them was half right, What the other person said is totally wrong. Using logic algorithm to analyze where Professor Wang is from (please provide detailed process,)
