"Searching for Him a Thousand Times in the Crowd" (眾裡尋他千百度) by Diamond Zhang is the love theme song of the 2026 Chinese costume drama "Pursuit of Jade," released on March 25, 2026 through Sony Music. The song's most distinctive feature is that its lyrics are drawn directly from "Qingyu'an: Yuanxi" (青玉案·元夕), a timeless classic by Southern Song dynasty poet Xin Qiji, with music composed and produced by acclaimed music director Dong Dongdong and arranged by Yan Tianwu. Known as the "OST Queen," Diamond Zhang brings her warm, richly textured and story-driven voice to perfectly merge the deep emotion of a thousand-year-old poem with the drama's tale of a marriage-first, love-later destined romance. The iconic line "I searched for him a thousand times in the crowd; turning back, I found him standing where the lights grew dim" captures a longing and searching that transcends time, making this a moving piece where classical poetry and modern pop intertwine.
