The very same pictures has been posted around at different websites and in other forums for some years now. No family name on this 'Tony' actually no nothing at all. He is most probably a fraudster on the run from the law and/or debt holders in the UK and need donations from charities back home for his so called voluntary work in China.
Why is there nobody in China that can tell anything about this guy? It's all in his words an some photos anyone can arrange. I don't believe this story until it has been proven in some way.
