Can I trade cryptocurrency in China?

I'm just wondering, can I engage in cryptocurrency trading in China? I've heard different opinions about the legality of it, and I'm not quite sure where to stand. Is there a clear-cut policy or regulation that governs this matter? If so, what are the main points I should be aware of? Also, are there any specific exchanges or platforms that are officially recognized for cryptocurrency trading in China? I'd appreciate it if you could provide some clarity on this issue.
