Ku Kuan-Chung Birthplace?

Recently, I have been researching and looking into more information about Ku Kuan-Chung. I noticed that on his page in the biography section that it says that he was born in the Guangdong province of China. However, I came across an interview with various articles in a Chinese magazine that was cited as saying he was born in Hong Kong. I was wondering if this is something that needs to be looked into! I know that this website strives for accuracy and this may need to be modified if it turns out to be true. It would be appreciated if someone would help clear this matter up. I thought it was best to bring this to light in hopes to double check that what information is right. Does anyone have any thoughts? Below I will attach the picture from the magazine that was cited as having that information in it:
