Bi Ran: public information is limited, and currently only the Chinese byline and three works held in the library are known; details such as birth and death years and nationality remain unclear. Judging from the distribution of these works, the author's writing spans several fields. The documentary work Eagle Chicks Flying Over the Pamirs is set against the Pamir Plateau and carries a distinct regional flavor and humanistic concern. 5G Core Network and Key Security Technologies belongs to the industrial technology category, indicating some engagement with communications networks and security issues. Don't Believe Everything You Think: How to Stop Thinking and Overcome Anxiety, Self-Doubt, and Self-Sabotage falls under applied psychology and addresses ordinary readers dealing with everyday psychological troubles such as anxiety and self-doubt. These three works correspond respectively to documentary writing, technology, and psychological self-help, suggesting that Bi Ran is an author with a broad range of subjects who can handle both specialized content and writing for a general audience. Owing to the lack of biographical materials and personal statements on writing, a systematic assessment of style and influence is difficult, and readers may judge for themselves from the works.
