《宋史·列传·卷八》
王溥任宰相时，王祚以宿州防御使官衔居家，每有公卿到他家，一定先去拜见王家，王祚摆酒宴庆寿，王溥穿着朝服侍奉左右，坐客不敢安坐，都起身回避。
溥在相位，祚以宿州防御使家居，每公卿至，必首谒。祚置酒上寿，溥朝服趋侍左右，坐客不安席，辄引避。
When Wang Pu was Chancellor, Wang Zuo resided at home with the rank of Defensive Envoy of Suzhou. Whenever a high-ranking official or noble visited his home, they would first go and pay their respects to the Wang family. Wang Zuo would hold a banquet in their honour, and Wang Pu would put on his court robes and serve on the side, while the guests would not dare to remain seated and would all get up and avoid him.
