Jian Yifan is an author about whom little public information is available; only one work by this author can currently be found, namely Ex Strategy. Judging from this work, Jian Yifan's writing falls mainly within the genre of contemporary romance, focusing on the advances and retreats, entanglements and complications of men and women in modern urban relationships. The theme of the "ex" itself carries strong emotional tension, often involving rekindled old feelings, attempts to repair a relationship, or the need to say goodbye to the past. The author's choice of such a point of entry suggests an interest in observing those subtle, awkward and unavoidable moments in urban emotional life. Because only this one work is available in the database, there is not yet enough material to judge the full range of the author's writing style, nor to confirm whether the author has written in other subjects or genres. What can be confirmed is that Ex Strategy, as the representative work, is the main gateway to understanding Jian Yifan's creative profile; readers who wish to know this author may begin with this book and see how the author handles emotional relationships within the framework of contemporary romance.
