Very happy for you sir! You've made it through the hardest part (supposedly) and your family is growing in what seems like a very positive way!
As for the pipes, being of Asian-American heritage, I can tell you the Chinese want to do 2 things: Make $$ and make it easy to get it from you. On behalf of the Chinese, I apologize for the state of things to a western disposition, but you have to understand it's a complete and pervasive cultural paradigm.
They will make things look more western, so they'll be more accessible. In the case of crafted goods like a pipe, you are not likely to know the "good" from the "bad" by name only. Nothing is sacred; you can get some nice deals, but more often than not things will be knocked off. :suspect: You're probably already wary of things, so I guess my advice is to aim low to avoid disappointment. :|
I understand that you're looking for a special commemorative item, but I don't know if it'll be quite up to par as the rest of the pipemaking countries of the world. The fact that the shop carries "other" makes might be promising, but you'd never until you smoke them and then is there any recourse if it doesn't turn out right? I guess that's the case for most things both abroad and domestically (USA for us I mean), so good luck!
Besides, couldn't you make your own "Chinese" pipe when you get back?
Just judiciously use bamboo and...
