New Mao biography

Just bought the new biography about Mao Zedong, by Jung Chang and Jon Halliday. I already read three biographies about Mao before, one by his body guard Quan Yanchi, one by his doctor, Li Zishui, and one by Jonathan Spence. So, I am very curious to see what new information Chang and Halliday came up with. There is already a lot of publicity around this book in the media ("Der Spiegel" even devoted their main article to it, last week). I wonder what reactions it will cause in China, because, no doubt, it will be forbidden there. I will check out some China blogs in the coming weeks on this issue.
