BEIJING — In the annals of people who have struggled against Communist Party rule, Wu Dianyuan and Wang Xiuying are unlikely to merit even a footnote.

The two women, both in their late 70s, have never spoken out against China’s authoritarian government. Both walk with the help of a cane, and Ms. Wang is blind in one eye. Their grievance, receiving insufficient compensation when their homes were seized for redevelopment, is perhaps the most common complaint among Chinese displaced during the country’s long streak of fast economic growth.
