I was reading the 2 books about Mao. Mao, A Biography by Ross Terrill. Mao, A Life by Philip Short. Both books add up over 1000 pages. There is a saying that "tomorrow is a mystery", but for Mao, it would be much appropriate to say "history is a mystery". you can peek through the books, and know some brutal facts based on what the authors are trying to tell. However, you might have another doubt, "what's real?", and feel lucky no part of those revolutionary days.
