TW: death and miscarriage
I've been to a couple of funerals in Asia and it is the custom here that you do the funeral and then the cremation. A day or so after the cremation close relatives go to pick up the urn but you get the remains in a big bowl and take it in turns to ceremonially transfer a bone fragment into the urn. The person in charge will point out which bone fragments are which. I think there is a special way they're supposed to be packed with eg the pieces of skull on the top.
Sorry if this sounds really morbid. I don't think it's done like this in the UK, is it? I have never been to a close relatives funeral in the UK. I had seen pictures of this ceremony for DH's grandparents funerals so I was not shocked when we did the same for MIL. Most recently, and tragically, DH and I did this for our miscarried baby but we just watched the crematorium worker do it as only the generation below the deceased should transfer their remains so he said we shouldn't do it.
