Book excerpt: In the dynastic history of China, Wu Zetian was the one woman who attained the status of emperor in her own right. A stone tablet marking her mausoleum was left blank, reportedly at her request because she wanted the future world to assess her. And her rise in the patriarchal system supported by Confucianism did later inspire many novelists and playwrights. Dien's slim study looks at the rise and achievements of the historical empress, her influence in the form of defiant woman who appear in legend and fiction, and (very briefly) the state of urban gender equality today.
