Saw this article on how other cultures celebrate Christmas. Nice little insight. :) Although in that titbit, he mention the Chinese pronunciation, and it's in Mandarin
It is Dun Che Lao Ren (dwyn-chuh-lau-oh-run) or "Old Man Christmas"
In Cantonese, it is Sin Dan Lo Yaan.
We just put up our tree (well my brothers do), and have a big Christmas dinner with the staff on the 24th, and open our pressies when we get home. Then family dinner on 25th. That is because the restuarant is normally closed for 2 days (out of the 3, the other one is Chinese new year).
Is it similar to other Chinese overseas? Since there are no comments here, you can discuss this over at IBC messageboard.
