In "The Scholars," the classic 18th century Chinese novel on the lives and misadventures of Ming Dynasty literati, there is an episode that departs unnervingly from the book's satirical, moralizing tone. One day the Nanjing scholar Chuang reluctantly obeys a summons to consult with the emperor in Beijing. On the way to Beijing he meets a fellow scholar, Lu, who excitedly tells him of a banned book he has just purchased, written by a scholar unjustly executed 160 years before. Chuang praises Lu for his "respect for learning", but warns his new friend to avoid "forbidden books."Nevertheless, he invites Lu to stay with him when he returns to Nanjing.

Back in Nanjing, Chuang keeps his promise to host Lu. But not long after Lu's arrival, hundreds of soldiers arrive and swarm over Chuang's estate; their commander orders Chuang to tell him if a scholar possessing a forbidden book is staying there. Lu surrenders himself, but in the following days Chuang works his Beijing connections to get Lu released. This story conveys vividly the vulnerability of scholars to a state authority that spares no expense to hunt them down if they stray from its narrow orthodoxy.

Chinese academics now struggling under what the Scholars at Risk Network describes as systematic Chinese government policies intended "to constrict academic activity and to intimidate, silence, and punish outspoken academics and students" might find much to relate to in Wu's story.
