《汉书·传·扬雄传下》
今年在长杨打猎，先命令右扶风，左到太华右到褒斜，砍载岸作弋，绕南山布置，林莽中排列千乘，山脚分布着上万骑兵，率军踏围场，赏赐戎狄禽兽。
今年猎长杨，先命右扶风，左太华而右褒斜，椓嶻而为弋，纡南山以为罝，罗千乘于林莽，列万骑于山隅，帅军踤阹，锡戎获胡。
This year in Changyang, he ordered the Right Prefect of the Wind to take a large area extending from Taibai in the east to Baoxie in the west, cutting down trees to make arrows and setting nets around the Southern Mountain. There were a thousand chariots lined up in the forests, and tens of thousands of cavalry at the foot of the mountain. They led the army into the hunting grounds, and rewarded the barbarians with birds and beasts.
