《韩非子·内储说上七术》
应侯对秦王说： 大王占领了宛、叶、兰田、阳夏几个地方，拦腰切断了河内，围困了魏、韩，之所以到现在还没有称王天下，是因为赵还没有顺服。
应侯谓秦王曰： 王得宛、叶、兰田、阳夏，断河内，困梁、郑，所以未王者，赵未服也。
Yinghou said to the king of Qin: The great king seized Wan, Ye, LanTian, and Yangxia, blocking he Nei in the center and besieging Wei and Han. The great king hasn't become the king of the world because Zhao hasn't succumbed.
