Sharifah --
If you include the name (or the website link) of the Guangzhou hospital in your next posting, that would enable people here to do their own searches and check out its claimed success rate.
Also, when I first became part of OCF two years ago, there was a woman posting here who had been treated successfully in Hong Kong in 2001. Through the User List button at the top of each page, search for the username karenng -- clicking on her name will give you her profile, which includes her e-mail address. Perhaps she can be helpful.
