Christmas is becoming a more and more commercial holiday (in my personal opinion). In USA, it's the biggest religious day and the most important holiday to swap gifts!
In China, it's just a one more great excuse for business people pushing their goods.

Eastern Department Shanghai, China - Dec 20, 2002... Isn't it cool?!
... people don't set up Christmas trees at home though... no gifts ; no special dinners either!

Danbury Fair Mall, CT - Dec 21, 2003
2 weeks before Christmas, people here already became panic in shopping, every exits from high ways to Malls could be jammed, and you might drive round and round in the parking lots of malls for over half hour to look for a spot to park.
