Jim,
I've heard similar stories. Not for Chinese New Year, but even just showing up. If the family isn't well to do, the relatives may be looking for handouts. The other thing is if you do go, how much money is appropriate. They will have a value in mind, most likely much more than you'd be willing to give.
A prime example would be Chong. Look at what the guy who introduced Chong to his wife wanted.
I'm not saying the relatives will all be greedy, but I have heard enough stories in the global chinese community of similar things.
Now if you want to give out lots of money, that's a different story. :icon_cheesygrin:
