<font color="119911">hi Hee, I'm no expert for sure but here's what I know:
1. Pin Jin is really up to what your mum wants. It can range from a yi shi of $188 all the way to $8888
For me, my mum asked for $3888. Then your mum has to return a portion of the money for your FH.
2. Guo Da Li usually takes place 2-3 weeks before the wedding (can be earlier if you want). People usually seek a fortune teller to get a good date to do this. Bride cannot be around when it happens. Traditionally, a mei po (or matchmaker) will bring the "goods" over to the bride's parents as a form of gift-giving. The "goods" can include things like oranges, cakes, etc etc. Again, it depends on what your mum wants. My mum only wanted the cakes and oranges. The cakes are for your mum to give your relatives when she passes them the invitation card.
3. An Chuang: This is the placing of the new bridal bed. Again, an auspicious date is usually sought for. Then a happily married couple with kids (usually your parents are used) will place the mattress on the bed. After this is done, no one can enter the room except the bride and groom BUT cannot even sit on the bed hor.
This is all I know and I'm sorry if I got some things wrong cos I'm not really practising these things. This is what I know from hearing from my friends who've been through it
Hope this helps</font>
