During a four-hour interrogation at the Nan'gao police substation in Beijing, Liu Yanping (刘艳萍), a worker in Ai Weiwei's studio, was verbally abused in obscene language by a man who said that he was not a policeman, but a "hooligan, auxiliary police." The man threatened to beat her up "outside" and "mess with" her husband if she discloses the interrogation on the Internet. The interrogation included detailed questions about the compilation of and posting online the names of the victims of the 2008 Sichuan earthquake, a project that Ai Weiwei initiated, and the artist's activities.
