Lee San-San (1) See the English Alias!

is it all the same IMO ?

The second and third seem like they might be the same person, though what a drop from good Hong Kong pictures to DTV drek like LEGEND ABOUT HUNTING GHOST! It would certainly make her the biggest name in that entire series.

Awful big gap between the first one (Shirly Lee) and the other two, though . . .

There seems to be 2 李珊珊, the more prolific one has a DOB of 10/9/1977 according to the HKFA or 10/14 (baidu.com) .

HKFA also links the first 李珊珊 with Dirt (1996), this is the one called Shirley Lee

and the 1986 Tong(o) - Chinatown Story

The later Lee San-San was also the winner of the 1996 Miss Hong Kong Pageant, no English name specified.
