I think Lau Lai-Gwan,
who played She Woy Jeng, alias Mrs. Ng Si Bo, in Great Shanghai 1937 (1986),
is the same person as Li Ai-Qun (alias Lee Ngoi-Kwan),
who played "Great Dancer" Yin Mu-shang in Hidden Hero (1990) and Princess Jade in Journey to the West (1991).

I have temporarily added 11 portraits of Lau Lai-Gwan to the image
section of Great Shanghai 1937 (1986) to help ascertain whether
Lau Lai-Gwan is the same person as Li Ai-Qun (alias Lee Ngoi-Kwan).

Sorry - should have responded here...
I think those are two separate actresses. Eyes and noses are totally different.

Oh well. It's really just their smiles and chins and name
similarities that I was thinking about. I thought that the
eyes and noses could have been the result of different
styles of make-up.

I'll remove 9 of the 11 Great Shanghai 1937 portraits, now.
