I'm looking for a good book on Chinese civics. I know the very basics of how the government's structured, but I want to go more in-depth.

So far I've found ebooks for The Government of China (Yu Bin), Chinese Politics and Government (Sujian Guo), and Understanding Chinese Politics (Neil Collins). I'm also looking to find a copy of Modern Chinese Government (Qianyou Zhang) but I'm not optimistic.

Is anyone familiar with any of these? Any recommendations?
