All three are essentially editors. I suspect that they are the same person although their last character is different.

Hope someone can confirm.

According to WebPAC...

Yiu Tin Hung (1) 姚天虹 and 姚天紅 (3) are the same person. The last symbol of (3) is not correct, probably the editor added it wrongly.

虹 紅

But Yiu Tin Hung (2) 姚天雄 is not (1). Actually (1) is director and editor, but (2) is only editor. His work as director in the film "The Survivor" is practically the chinese re-edition of a HK-japanese softcore movie directed by Yukio "Kobuku" Kitazawa. In this korean site you will find him with his correct symbols, for the film "Never Say Regret": http://www.joycine.com/kool2/m_search/v ... movie=4553

Well, this is what WebPAC says.

any other opinion?
