I've got a bunch of books on Modern Chinese History, but I don't really know if I'm missing anything crucial. I've Jung Chang's Mao and her other book on the three sisters. I've got Frank Dikkoter's trilogy along with his new book "China after Mao". I've got "Imperial Twilight" and the Spring and Autumn book the same writer made. "Empress Dowager Cixi" is in my collection along with "The Generalissimo". What am I missing?
