《史记·七十列传·卫将军骠骑列传》
于是皇上说： 剽姚校尉霍去病杀敌二千零二十八人，其中包括匈奴相国和当户，杀死单于祖父一辈的籍若侯产，活捉单于叔父罗姑比，他的功劳，两次在全军中获第一，划定一千六百户封霍去病为冠军侯。
於是天子曰： 剽姚校尉去病斩首虏二千二十八级，及相国、当户，斩单于大父行籍若侯产，生捕季父罗姑比，再冠军，以千六百户封去病为冠军侯。
So the emperor said: Piao Yao General Huo Qubing killed 2,028 enemy soldiers, including the prime minister of the Xiongnu, the ruler of the horse administration, the uncle of the oldest ancestor of the Chanyu, and the nephew of the Chanyu, Luo Gubi. His military accomplishments ranked him as the top in the whole army. 1,600 families were separated, and he was made the Marquis of Champion, Huo Qubing.
