Rong'an Yiwang is a Chinese web-fiction author about whom little public information is available. Only one work can currently be confirmed, the novel Nüguan (Female Official). Based on the available information, the work falls into the time-travel alternative-history category, suggesting that the author builds the narrative around a time-travel premise and an invented historical setting, with a focus on the ancient officialdom and the circumstances of its characters. The title Nüguan hints that the story may center on the identity, duties, and survival of a female official, but no public materials are available on the specific plot, character design, or writing techniques, so no further inferences should be made. As far as the existing work shows, Rong'an Yiwang is still at the stage of a single published work, and readers' knowledge of the author and the writing comes mainly from Nüguan. Since the author's nationality, dates of birth and death, and English name are not public, this introduction is limited to the facts in the database and the work's category, and further biographical and creative details await additional materials.
