《资治通鉴·唐纪·唐纪十四》
辽泽一带道路泥泞，车马难以通行，太宗命长孙无忌率领一万人割草填道，水深的地方用车做桥梁，太宗亲自将薪木等拴在马鞍后帮助铺路。
辽泽泥潦，车马不通，命长孙无忌将万人，剪草填道，水深处以车为梁，上自系薪于马鞘以助役。
The roads in the Liaoze area were muddy, making it difficult for vehicles and horses to pass. Taizong ordered Zhangsun Wuyi to lead 10,000 people to cut grass to fill the road and use carts as bridges in deep water. Taizong himself tied firewood to the saddle of his horse and helped pave the road.
