A combination of cheap domain names and a largely unregulated TLD, HuskyPup,
Basically the cost of the domains made them disposable so they had a massive rise in the number of .cn domains. I think that the Chinese government also needed the .cn ccTLD to be seen as competing with the super ccTLDs like .de and .uk for the Olympics. Its growth made it look impressive but most people realised that it was a bubble. The 28/Febuary count for .cn was 3,379,441 so it is still continuing to fall. Many of the junk (terrible pun) domains have filtered out of the zone but there still will be a few more to go. What is very interesting about the .cn ccTLD is that the registry has effectively changed it from being a largely open TLD to a managed TLD where some element of entitlement has to be demonstrated by a registrant. The .de has this to some extent with the requirement for a local contact for .de domains. Managed registries (where some entitlement has to be proven) tend to grow slowly and have a lower number of registered domains. Less stringently regulated TLDs have higher numbers of registrations but with their low cost, they lose some of the incentive for registrants to develop websites.
