Read this book called “Life and Death in Shanghai” by Nien Cheng a while back. Honestly I should not putting in these terms, if you consider the sufferings of the author, but it was breath-taking, thrilling read. Just how bad and ludicrous it can be. If Nehru had access to such accounts, he’d have done better than trust Chinese communists with any consistency in their policies. China’s attach on India seems like a trivial shift in policy compared to swing that took place all the time in Maoist China. High profiled leaders being denounced mercilessly, when it suited some other who happened to be in power then, the hypocrisy of the regime and the plight of those having a disadvantageous class origin. Sigh! Although its a thick book, give it a read sometime. Its kind of difficult to stop once you have started reading it.
