The Detective Project-To Chase One's Tail Training, implemented by Zhou Xiaohu in August of 2008 is a premeditated monitoring test. After signing separate contracts and paying the required fees, 10 private investigators from 10 different private detective firms got busy playing the game designed by their employer, Zhou Xiaohu. Each of the investigators immediately began the serious investigative work by following the person appointed by his or her employer without ever knowing that he or she is being investigated and followed at the same time. Only their employers, who are in receiving a steady stream of reports and looking down on them from above, know that this is a loop of information that feeds on itself: everyone is snooping and collecting information about someone, yet everyone is also being snooped on and having their information collected.

Detective Project-To Chase One's Tail Training was conducted in crowded shopping malls and subway stations. Ten busy investigators were paid according to their investigative abilities according to the contract they signed before the investigation. After aesthetic transformation, the artist Zhou Xiaohu posited the process of the entire operation into the museum, a space for viewing and reflection, which raises a series of questions: Which channels and methods can personal information be obtained without having been publicly disclosed? What is the client's reaction when he finds that he is being investigated and followed by another private detective company? What will happen when the information of the parties is published without their knowledge? "Do unto others as you would have them do unto you" When the investigator is also the respondent, and when the investigator finds they are also being investigated, and everyone becomes aware that they are both the investigator and the respondent, what subtle changes will happen to the questions asked?

As circumstances change with the passage of time, the technology implemented in Detective Project-To Chase One's Tail Training has already become outdated, but the basic logic of the situation and the issues addressed all relevant to contemporary life and continue to on in the form of video surveillance, facial recognition, big data, 5G, and artificial intelligence. Of course, it can also be that these prickly topics have been smoothed out by new life experiences…
