For some reason these two links come up with blank pages.



Also, Chan Wai-Ling (2):


from Jade Hairpin Alliance, is this her?

Sorry, my fault. Fixed.

Regarding Jade Hairpin Alliance, I think this looks more like her, but I'm not sure:

What character is that? Nau Nau's assistant? This girl?

Would she be a credited character? The one I thought has a somewhat major role in the film.

I took another look at the film, and I think you are probably right about Chan Wai-Ling (2); in the film she is probably the sister of Wong Man-Chuen. Another bit of evidence, is the fact that those two are in almost all scenes together, and their names are together in the cast list.

Perhaps the resemblance to Chan Wai-Ling (2) is strongest in this comparison

but I'm not totally sure.

I think that's pretty conclusive as well. I've added her name to that portrait and updated the role.

thanks
