I agree, Deanna, I found that to be really eye-opening, and it really made me think about how a big part of the Cultural Revolution was abolishing all those "old-fashioned" ways of thinking that were so deeply ingrained into Chinese thought. I recently read "The Last Eunuch of China," and this concept reinforced even more what a terrible fate that was, in addition to all the physicial and emotional trauma, the inability to have children was the inability to live on into eternity.
