Pei Ju
In 604, Emperor Wen died—a death that traditional historians mostly believe to be a murder ordered by Yang Guang, although they admitted a lack of direct evidence—and was succeeded by Yang Guang (as Emperor Yang). Emperor Yang soon started the reconstruction of Luoyang to serve as the eastern capital, and he put Pei Ju in charge of building the governmental offices, which Pei completed in nine months.
