Da Xiao Jie (大小姐; also known as Frances & Aiko, Big Missy, Ojou-sama, or Big Small Sister) was a pop duo. The duo consisted of two young Chinese girls named Wu Zhao Xian and Lan Ai Zi. The two girls were found when they auditioned at the Taiwan NEW STAR auditions which were held to find members for a new Taiwanese group to allow Hello! Project into the Chinese market. They were deemed too young to participate in Ice Creamusume and didn't make the final cut. They were originally signed to Hello! Project Taiwan. The duo was managed by Forward Music in Taiwan.
