Whether the book publishing agent on Douyin is reliable requires comprehensive consideration of multiple factors. First of all, Douyin is a social entertainment platform, not a professional book publishing or agency, so you need to be extra cautious when choosing a book publishing agent on Douyin.

Secondly, you should conduct in-depth investigation and research on the platform for book publishing agents, including its registration qualifications and credibility, the types and quality of books published by agents, publishing processes and costs, etc. You can find the company information and credibility of the agency or platform through user reviews, public litigation cases, media reports, etc.

Finally, you also need to be wary of some agencies or platforms suspected of illegal activities, such as suspected piracy, illegal pyramid schemes, etc. If you find any problems, report them to the relevant departments in a timely manner to avoid losses and impacts.

In short, when choosing a book publishing agent for the Douyin platform, it is necessary to carefully analyze customer needs, the credibility of the agency platform, the quality and authority of the agency books, and other aspects, and conduct a more comprehensive investigation and research through multiple channels to ensure the reliability and legitimacy of the selected agency platform and publishing organization.
