The stalk of Chaoyang refers to the Chaoyang people, and the stalk of Haidian refers to Haidian netizens.

Chaoyang people refer to the residents of Chaoyang District, the capital of China, who have participated in cracking many major and important cases such as celebrity drug abuse, and are called "Chaoyang people" by netizens.

Chaoyang District is the largest area in the urban area of Beijing. In fact, the figure of "Chaoyang people" can be seen everywhere. They may be security guards in shopping malls and supermarkets, volunteers on the roadside, or just ordinary passers-by seen in morning exercises.

"Haidian Netizen" is a "mysterious organization" that exists in Haidian District besides the "Chaoyang people" and "Aunt Xicheng" that have been well known to the public. They hide behind the screen of computer mobile phones and provide all kinds of clues to the police anytime and anywhere, but the police handling the case have rarely seen their true colors. According to the characteristics of this group, the police gave them a nickname "Haidian Netizen".

Since August, 215, Haidian police have paid 1.5 million yuan in bonuses to more than 3, "Haidian netizens", but more than 9% of "Haidian netizens" voluntarily gave up the rewards.

Although the base of "Haidian netizens" is larger, most of them are behind-the-scenes heroes hidden behind the screen of computer mobile phones. The clues given by Haidian netizens are not limited to the region where they live. As long as they hold their mobile phones, Haidian netizens may appear everywhere.

Haidian netizen, who is also called "Four Mysterious Organizations" with "Aunt Xicheng", "Chaoyang Masses" and "Fengtai Persuasion Team", is perhaps the most mysterious-since the beginning of 216, more than 3,1 pieces of effective information have been provided to the police, but sometimes even the police handling the case don't know the true face of netizens who provide clues. They hide behind electronic devices, observe the real and virtual worlds, and help the police eradicate crimes in the "two worlds".

"Haidian netizen" is not only a "well-known trademark" in Beijing, but also has a world-class influence. It was netizen Gu Men (a pseudonym) who helped the police defeat a cross-border hacker gang that infected 25 million computers. This case is called "Fireball".
