Recently, an investigation by the 5GH Team has revealed that several companies in Nanchang are suspected of selling academic papers. These companies attract customers on RedNote (a.k.a. Xiaohongshu), a well-known Chinese social media platform, through advertisements for "journal recommendations" or by posing as past clients sharing their experiences. Ultimately, under the guise of professional technical services such as copyright transfer services, the companies provide ghostwriting services to clients, in suspected trading of academic papers.
