As early as 1992, the first private detective investigation agency appeared in mainland China. Ten years later, the Trademark Office of the State Administration for Industry and Commerce adjusted the scope of trademark classification registration and included the original 42 categories of goods and services. Trademark registration has been expanded to 45 categories, among which the newly allowed registration categories include the provision of private insurance, detective companies and tracing investigations. The country officially began to allow citizens to register private detective trademarks in 2003. With the rapid development of society, the market demand for private detectives has also been expanding in recent years, and the private detective industry has developed rapidly. According to statistics, there are approximately tens of thousands of private detective agencies in China, employing more than 100,000 people. However, due to the lack of necessary thresholds and effective supervision, the composition of industry personnel is chaotic, which in turn hinders the healthy development of the private detective industry.

China Detective Network was successfully launched in 2011, aiming to promote the steady development of the industry while creating a real, professional and confidential communication platform. The first phase of the website project consists of: News Center, Detective Rules, Legal Consulting, It consists of ten modules including business investigation, marriage investigation, debt processing, person tracing and evidence collection, case analysis, detective equipment, and detective company. The second phase of the project will create a fully functional membership system to provide more convenient services to the general public.

The classified information in the detective company breaks the traditional search method and uses more convenient and flexible technical means to create a more convenient model for customers.
