I've done a few different types of Buddhist funerals.
H'mongs keep their ceremony going on for three days.
(I can be confusing cultures with their religion, but, I am pretty sure they are mostly Buddhist). Generally a lot of flowers and will spend the price.
It's a pain to keep the flowers going for 3 days, lot's of upright sprays, but I do. I'll go to the funeral home once a day to refresh.
More relaxed Buddhists funerals - Shinto - generally take place in their temple, at least here in Denver. Again,a lot of flowers. Lot's of upright sprays. Intense cedar burning going on. Lots of color. One service.
I just googled the Hmongs and see that they have they own religions with shamans as spiritual guides. I see men performing rituals during the 3 days, now I know.
