you do seem to have a very complete cast list but let's see if we can crack some additional nuts here for my friend who is researching the movie.

Louis Roth obviously and my friend ID this woman as Therese Tuatanne (Tuatonne alt. Related to Vincent who IS in the film). Seem correct?
MR CHAN who buys the ginseng looks in this cap like Lau Shun but that's a long shot on my behalf. Anyone? Mrs. Chan is credited FYI.
The maid who tells Anita about the return of Jackie and Dick. Very pretty and classical face, yet no name, no character name....Not Chen Gei Ying as she has credits going back 10 years from this production. Child actress prior?
