mrslong, for one month, I've received before those traditional cakes (actually not very traditional.. there's kueh and red eggs and cakes inside) with a card with BB's photo on it and another more modern one is a specially designed box with a small bottle of hot chocolate, mix nuts, green tea and cookies.. all packaging has this sticker with the bb's photo on it.
Those are received when ang pao goes but no one month celebration done.. For those who have buffet and invite ppl to go to their hse, so far I did not receive anything. The food catered is more or less the only thing.
Oh.. all the house parties for one month celebration got no balloons.. those older birthday parties will have.. but think they buy off the shelf.. cos most of them are those metalic helium balloons.
