I came across this interesting article from Austrian Futurezone citing some leaked document from the Chinese government and what exchanges have to do after shutting down:
If your German is not too good, you might be delighted to hear that one of the steps is to hand over all information about their costumers to the Chinese Government. I hope no one has given them any important data.
Also very interesting: China has only banned local trades of Bitcoin in Yuan, but has left international trades legal. Why might that be?
