Hi gin
I not to sure abt others. At least for my family, roast pig is only on AD. After I marry over to FH house, tea ceremony, change to Kwa, then bring the roast pig home.
My mum will then return the pig head and back, together with a new pants to my FH.
Jia zhuang is not SDJ. SDJ is given by my FMIL. Jia Zhuang is prepare by my mum.
My list of Jia zhuang
1) pillow/bolster
2) blanket (I replaced with quilt cover)
3) new bedsheet/pillow cases
4) sewing machine
5) bridal chest (replaced with luggage) - to put new cloth, undies, etc
6) baby bath tub/ face basin
7) potty
8) mug
9) toothbrush/toothpaste
10) 1 pair New bowl/spoon/chopstick
11) 1 pair of chopstick (to open mouth for baby in the future)
12) zi sun ruler (as we dun have the comb hair ceremony, this will be brought over on Guo Da Li)
13) 1 pair of oil lamp (battery operated)
14) 2 pair of slippers (bride/groom)
15) 1 new set of pyjamas (for the wedding night)
16) 1 new teapot (for tea ceremony at FH house, must put lotus, longnan, red dates, etc)
17) 1 set of sewing kit in a box (to symbolise the bride can only do needlework, no HARD LABOUR work)
18) makeup set (I bought new lipstick, and powders)(to symbolise the bride can put on make up everyday, so no need to do hard work)
19) some barang barang for an chuang purpose
20) my kwa and shoes
21) ring pillow which i made (a piece of needlework the bride do)
22) 1 pair of new towels
On AD, then I will bring all my jewellry, including SDJ to FH house, to show that the bride is bringing gold to FH house, but I got to leave behind some gold for my two brothers, so as not to take away all the gold from "mother's" house.
My FH did not follow us around to distribute cakes. I don't think there is a need.
I personally dun like Yam Ring.
