Estimated: filming ran from 27 September 2025 to 10 February 2026, and the 26 episodes are reported to have been submitted for review, with iQIYI tentatively placing the drama in the fourth quarter of 2026 (blogger reports, not an announced date). Cheng Yi's two most recent iQIYI period dramas premiered about 9 months (Mysterious Lotus Casebook: wrapped October 2022, aired 23 July 2023) and 10.5 months (The Journey of Legend: wrapped 25 October 2024, aired 11 September 2025) after wrapping; the shorter gap from 10 February 2026 gives about 9 November 2026, inside the fourth-quarter window. No date had been announced by 27 September 2026, despite a new trailer at iQIYI's iJOY event on 23 September. Re-date when iQIYI announces the date.[1]两京十五日 (Liang Jing Shi Wu Ri, "River of No Return") is iQIYI's 26-episode Ming-dynasty historical drama starring Cheng Yi (成毅) as the crown prince Zhu Zhanji, who must race up the Grand Canal from Nanjing to Beijing in fifteen days, with Lin Gengxin (林更新) and Jiang Peiyao (姜珮瑶) in special appearances. It adapts Ma Boyong's novel, is directed by Zhang Li and wrapped on 10 February 2026. iQIYI has only pointed to the fourth quarter of 2026, so the premiere shown here is an estimate.
