if your cards writes: parents name so n so
together with your name so n so.
you have to address the relatives from the parents point of view.
if in english, mr n mrs so n so n family
if in chinese, you can write how you address the person like 4th sis
(si4 yi2) and family.
my mum also said that if the relatives are older than your parents, they would prefer the cards hand delivered to them.
which i thought was a bit mafan.
do any of you all do that?
