The illegitimate half-sister of the Yong'an Marchioness Bai Xiqing. She was believed to have died at eight years old but actually survived and was locked away by her sister out of resentment. She is described as thin, sallow-faced, frail, and trembling, having been tortured for years. She is timid and fearful, initially lacking the will to live or fight back. She fled her manor in search of protection at the Huguo Temple, believing that finding Wusheng there was fate, as his sacred artifacts could counter Bai Xiqing's demonic arts. She is suspicious of the Qin royal residence's motives in helping her, wondering if they are trying to draw something out of her. Despite her weakness, she is being pushed toward revenge by Wen Ruan.
