Hi, for me... I would buy those chinese ink painting...simple ones just black & white or with slight hint of red or gold. think that's add more chinese feel but without the loudness.
Can try to buy those rattan baskets for your goodies... also serve your guests with very 'china' floral pattern glasses that we used to drink F&N orange soda. I think TANGS Home has lots of nostalgic stuff to start with. If not, go hunt those small shops at old HDB estates.
