Residents living in Chaoyang District, Beijing were given the nickname of “world’s fifth largest intelligence agency”, by Chinese netizens due to their excellent intelligence-gathering ability.
A middle-aged woman Wang living in Chaoyang District reported a suspicious man who had unusual behavior to the police and helped the police to capture a place for illegal prostitution. 
Wang is an active member among the "Chaoyang masses." In May 17, 2017, when she was patrolling the neighborhood, she found a man suspicious. 
Wang discovered the man never went to work and always went in and out his apartment, acting in a furtive way. In addition, the man ordered a large amount of food everyday, while he seemingly lived alone, which drew Wang’s attention.

A mobile phone app “Chaoyang Masses” was launched by Beijing police in February, 2017, allowing more local residents to report suspicious cases to the police by uploading words, pictures and videos on the app.
A 27-year-old man Li Jun (pseudonym) discovered three suspicious men outside the gate of a shopping mall near the North Third Ring Road in Beijing, so he took photos secretly and uploaded them on “Chaoyang Masses” app, which helped the police to catch a pick pocketing group on spot, with seven mobile phones found and three suspects detained, Beijing Daily reported.
By the end of 2017, over 140,000 Chaoyang residents registered with their real names on the app. As the land area of Chaoyang District is 470.8 square kilometers, there are over 300 "Chaoyang masses" in every square kilometer, people.com.cn reported.
