Can someone double check the actress identified in the database as Isabel Chan in Colour of the Truth; I don't think that's her. She's identified as playing Blind Chiu's wife, but that doesn't look like her. In fact, this character's/actor's picture is on the Isabel Chan biography page, too.

In COTT, I thought Isabel Chan played the friend of Gillian Chung's character, the one who gets shot in the leg during the gun battle in the house. She's on screen only briefly, but if you pause it just as she's shot and before she falls, I think you'll see what I mean.
