These are .cn.coms and aren't a real ccTLD. cn.com is
just another .com domain owned by a private company called
CentralNic. They sell subdomains like example.cn.com to people
NOT .com.cn which are a part of the .cn ccTLD's architecture and controlled by the .cn registry.
If you heard about web.com, they used to do the same thing that Centralnic's doing with .cn.com. People could buy [sub]domains under .web.com, like example.web.com from them. Recently, they decided to take back all the .web.coms they sold.

If you bought one of the names and worse, if you developed a business on one of the domains, you were out of luck. Your domain, example.web.com would stop working and all your customers that only know to find you there would be lost. JUST because the company that owns Web.com decided to stop providing the subdomains...
Not that ICANN's much better.
