Hey! Hey! Hei!

Aloha 姑媽 & 姑姐s,

Guess who they are? I'll give you a hint. The 4-months young on the left looks very much like his own uncle when he was a kid (that 叔仔排行第四). Yes, the LauZ sibblings are related to the father of these two good-looking kids.
(Please put your guess onto the Comments (see the link on the bottom right of this entry?) and remember, use only your first name or first initial and no lastname nor email needed)
(Kids' dad, thanks again for letting us see the pic. Send up more when you have a chance, ok?)
