Shanghai is a bit far for me but if you guys drop by Shenzhen/Hong Kong, I'd love to meet fellow HNers.
Shameless plug for HNers in China: feel free to add me on Skype (o-lalonde) if you'd like to collaborate on some open source/commercial projects (Node.js/Javascript/Rails/...) or simply discuss. I'm currently on the hunt for a co-founder who'd be interested in doing a startup in China (I haven't settled down on an idea yet).
