《新唐书·列传·卷九十一》
到秦国集中精锐军队对付三晋，经过六代人的征战才占领韩国，因此折断了天下的脊梁；又攻占赵国，趁势扫平其他诸侯国。
至秦萃锐三晋，经六世乃能得韩，遂折天下脊；复得赵，因拾取诸国。
In order to Qin Dynasty concentrate elite troops to deal with Sanjin, it took six generations of fighting to occupy Hanguo, thus breaking the backbone of the world; it also attacked Zhao, and took advantage of the momentum to sweep away other vassal states.
