《资治通鉴·隋纪·隋纪八》
河东县户曹任对李渊说： 关中的豪杰都踮着脚盼望义军，我在冯翊郡多年，了解冯翊豪杰的情况，请让我去宣召他们，他们必定会望风而动。
河东县户曹任瑰说渊曰： 关中豪杰皆企踵以待义兵。瑰在冯翊积年，知其豪杰，请往谕之，必从风而靡。
Ren Dui, the Registrar of Hedong County, told Li Yuan: The heroes of Guanzhong are all awaiting the righteous army.  I was in Fengyi County for many years and I know the heroes of Fengyi very well.  Please allow me to summon them, and they will definitely join us.
