补充资料:木杆可汙(?~572)
中国南北朝时期,突厥汙国军事首领。伊利可汙之子,原名俟斤,又名燕都。智勇兼备,善于征战。西魏废帝二年(553)继立为突厥可汙。恭帝二年(555),消灭了柔然汙国的残余势力,后又东败契丹,北并契骨,威服塞外诸国。三年,与西魏合力破吐谷浑。他连年征战,使其汙国疆域东起辽海(今辽河上游),西至西海(今里海、一说咸海),南自今阿姆河,北到今贝加尔湖。建汙庭在于都斤山(今蒙古人民共和国杭爱山之北山),拥兵数十万,成为当时北方唯一强大的国家。北周保定三年(563),他集结精骑10万,会合北周大将杨忠所率步骑 1万,进攻北齐重镇晋阳(今太原西南)。时遇大雪,至次年正月不克,遂纵兵大掠而还。北周建德元年卒,其弟他钵可汙继位。
