Coming in late to the discussion about Vonnie Lui. First of all, great find! She's gorgeous! Obviously been around for a while, but never seen her before.
Before she was in Sexy Dolls, she was evidently in a group called 3G, which released at least one EP, available at YesAsia
here. It's also referred to on FeelHKRadio site
here. On the same site, she is also mentioned
here and as saying she will not do any 'Category III' (nude?) movies, right
here. Damn!!
She has her own little Geocities site right
here. (You have to look hard for the tiny navigation menu at the top). It mentions the EP and also seems to refer to 3 MVs by 3G (I don't read Chinese, so maybe someone can confirm... maybe they can be found and posted?) There are also some photos which she has placed on a WebShots album. Lots of photos though, but haven't had a chance to look through 'em yet - nothing very revealing, just lotsa shots for the true Vonnie fan!
