I'm needing to fill in some of the blanks, could anyone help me by providing birthdates and birthplaces for these actors?

Michael Chan Wai-Man
Andrew Lau Wai-Keung

I'll post more later, cheers.

Michael Chan was born in 1948.
Andrew Lau was born in 1960.
Both were born in Hong Kong.
Nobody knows the exact date.

...and judging from those wild tattoos on Michael Chan, as well as his kickboxing skills, if he didn't want to tell you his exact date of birth, he wouldn't have to!
