《史记·七十列传·春申君列传》
在这个时候，秦国已经占领了楚国大片领土，因为在这以前秦王曾派白起攻打楚国，夺取了巫郡、黔中郡，攻占了鄢城郢都，向东一直打到竟陵，楚顷襄王只好把都城向东迁到陈县。
当是之时，秦已前使白起攻楚，取巫、黔中之郡，拔鄢郢，东至竟陵，楚顷襄王东徙治於陈县。
At that time, the state of Qin had occupied a large area of the state of Chu, because before that King Qin had sent Bai Qi to attack the state of Chu, captured the counties of Wu and Qianzhong, occupied the capital city of Ying, and advanced eastward to Jingling. King Xiang of Chu had no choice but to move the capital eastward to Chen County.
