Six hours after being taken into the Ju Yuan Hotel, Anhui girl Li Ruirui was raped. The alleged perpetrator was one of the hotel "guards". At the time of the incident, more than 70 special "tenants" from around the country had already been brought into the hotel, crowded into the simple rooms within this gray courtyard next to Beijing's South Railway Station. After receiving the alarm, police who had previously investigated this hotel multiple times immediately intervened and controlled the suspect overnight. What kind of hotel is this? Why were people "guarded" here? And what happened to them in these gray simple rooms?
