Gu Yulou, originally named Liu Tingting, is a Chinese author of romance novels born in the 1990s. Public information about her is limited: neither her dates of birth and death nor an English name has been recorded, and two of her works are currently included in the collection. She commonly writes in the time-travel and alternate-history category, and her representative works include Sheng Ge Yao and Half a Life of Vanity, Half a Life of Leisure. In terms of style, Gu Yulou's writing is gentle and delicate, rich in poetic and pictorial charm, and she skillfully blends classical sensibilities into her narratives, for which readers have called her style “ci-fu style.” This label summarizes her distinctive way with words and reflects readers' recognition of the temperament of her prose. In her existing works, she mainly writes romance, using time-travel and alternate-history settings to build atmosphere, so that emotional portrayals and classical charm complement each other. Although information about the author's life is very limited, these two representative works show that she pays attention to the texture of language and the creation of atmosphere, forming a relatively distinct personal style within her genre.
