补充资料：姚枢(1201～1278)
元初政治家、理学家。字公茂，号雪斋、敬斋。先世自营州柳城（今辽宁朝阳）入居内地。少时学习勤奋。金朝末年，父姚渊任许州（今河南许昌）录事判官，徙家于许。1232年，蒙古军破许州城，姚枢到燕京（今北京）投靠杨惟中，被引荐北觐窝阔台汗。1235年，皇子阔出统兵攻南宋，诏姚枢从杨惟中随军访求儒、道、释、医、卜等类人才。蒙古军陷德安（今湖北安陆），姚枢从俘虏中访得名儒赵复,力劝其北上讲学授徒,此后理学在北方传布渐广。姚枢从赵复处尽得程朱传注诸书，始攻习理学。1241年,出任燕京行台郎中,旋因与主管官员意见不合，弃官，隐居于辉州苏门（在今河南辉县北）。1250年，忽必烈召姚枢至漠北访问治道，姚枢上书陈述儒家传统的帝王之学、治国之道，深受器重。忽必烈受命总制漠南汉地军事，姚枢建议在与南宋接壤地区屯兵，积谷守边，徐图灭宋，被采纳。后从忽必烈攻大理、鄂州（今湖北武汉），咨谋军中，屡谏屠戮。元世祖忽必烈即位后，姚枢以藩府旧臣预议朝政,参定一代制度,任东平宣抚使、大司农、中书左丞,出为河南行省佥事,入拜昭文馆大学士，终于翰林学士承旨职位。
