For the most part, the Changchun Friends website is not very active and has been superseded by the Tencent "Wechat" app by the local expat community. This website is maintained sporadically, people may still join and membership is still open, but if you are a spammer, stay away. The archived information here is still useful, but some may be out of date. There are plans to make it more useful for static information in the future. If anyone needs information about Changchun or China, you may post a message and it probably will get a response but not immediately.

Changchun Friends

a great way to get involved

Suppose you're on a game show, and you're given the choice of three doors: Behind one door is a car; behind the others, goats. You pick a door, say No. 1, and the host, who knows what's behind the doors, opens another door, say No. 3, which has a goat. He then says to you, "Do you want to pick door No. 2?" Is it to your advantage to switch your choice?

Wim - you are not allowed to enter!

I have read the answer and I still don't get it!

I know the answer like Wim and John so don't want to spoil it. I will wait till the end. When is the dead line?

NO.1

Like Wim, I know the answer too.  However, given gas prices, getting a goat may not be such a bad thing.

OK what will I get if I answer correctly?
