Here's a thread I found on another forum regarding the family relations of HK and TVB actors.

There's some that I know already, and yet, there's still some actors that I did not know were related to each other. Does anyone have time to retype the list from this site without the pictures? Just want to see a neat list, the pictures is a too big.
