Good detective work bro, i also have the picture sets of Aum and to be honest i think it is Annie Chui regardless if you look at the picture in the first set of her lying on the sofa that is unmistakably her without a doubt, even the moles on the breast are the same.Maybe she didnt work with that photographer under any other name but then again he will also probably say she never did hardcore porn either !!!
The only people to confirm this either way are the A4U photography staff and her model agency or manager (thats the dude to track down) put it like this Annie Chui has never been on anything since A4U. A lot of the other A4U models (nancy ho and irene fah ect ect) have but not her, she is seriously popular and has done zero work since?? i dont think so, living in Asia for so long i know that theory runs counter to the law of Asian economics. She is either dead or retired from the industry which, lets be honest, seems unlikely given her popularity (read money making potential)
Aum = Annie Chui = Dead.
Regardless of what the photographer guy says, ask my mate Varnish and i am sure he will agree as he is the main man on all things Annie chui. Maybe the staff of the black alley could answer the question, or better still feature her if she really is still alive.
But personally i wouldnt hold my breath on it.
