How can I get a message to Ruby Yang?

A relative of mine is a retired real estate developer from Shanghai, living in Canada. Recently he told me he is going back to China next month to continue the process of getting approval for building housing for orphaned children,his focus in his retirement years. I told him about the movie and he is very interested in contacting Ruby Yang who now lives in China. Does anyone know an email address, etc that he could contact her? Any suggestions otherwise would also be helpful and I will pass the information on. Thank you.
