Pearly> I am not very sure also. Only remember my mum mentioned something like.. for GDL out of the full list she gave me.. she counted hw many she wanted for solely my own family.. ie.12 cans of porks, 12 boxes of cakes, 12 oranges, 2 bottles of wine, 2 pair of dragon & phoenix candle, the pingjin. She will return 6 cans of porks, 6 boxes of cakes, 6 oranges, 2 bottles of orange juice, 2 phoenix candles and part of the ping jin which my hb will bring on that day.
Those mentioned about are just for my family.. meaning.. my hb still need to prepare 24 boxes of cakes, 48 porks can and 48 oranges for my relatives. Hence, total list to my hb side will be 24+12= 36 boxes of cakes, 60 cans of porks, 60 oranges, 2 pair of dragons & phoenix candles, 2 bottles of wines and pingjin.
(these are not the real numbers, cause I didnt have the list with me.)
On the actual day, hb will still need to bring a tray/basket of orange, pork cans etc.. whether any returns on the actual day, I don't know.
