Who is the Duke of Zhou who interprets the dream

Duke of Zhou, surnamed Ji Mingdan, was the younger brother of King Wu of Zhou. Because his fiefdom was in Zhou (now north of Qishan in Shaanxi Province), he was called Zhou Gong or Zhou Gong Dan. 'Zhou Li · Tian-guan · Neizai' is called the job of Zayfu: 'Where the great sacrifice and general assembly of the state are the same, the handsome is from the deacon.' If the king is in charge, his decree shall be governed, and his charge shall be the king's.' Later, the world honored him as 'Yuan Sheng' and 'sage'.
