Wu Chengsi
Soon after Emperor Ruizong took the throne, Empress Dowager Wu carried out a major renaming of governmental offices and banners. She, who disliked the capital Chang'an, also elevated Luoyang's status, making it a co-equal capital with Chang'an. She further, at the suggestion of her nephew Wu Chengsi, built an ancestral temple for five generations of her ancestors and had Emperor Ruizong posthumously create them princes.
