china has chinese value which is different from western country. as individual person yang has own right to do anything he wants to do. But as chinese professor he is not. at least if I were mother, I would not send my child to the university where he was hired. he is bullshit , not worth our respect!!!!
Please leave Prof. Yang alone. Nobel prize winner - how many do we have of Chinese origin? Look at what Taiwan has done for Nobel Prize winners of Chinese origin (be it in Arts or in Science) - respect, respect and respect!!!!
