Beijing - can't read my blogs from here - censorship?

I am in Beijing, Jinan and Shanghai until the 4th of July.
I have been posting to my Jook-sing in the Motherland blog for a few days now. But an interesting thing is I can't access my blogs from here. It must be the censorship of certain sites by China's filtering mechanisms. Very interesting that I can access all the corporate sites likeWal Mart, etc. but I can't read my own harmless blogs, but at least i can post to them...
