《后汉书·列传·南匈奴列传》
他们用绳索连结，彼此悬吊上去，直通翻过天山，大败乌桓，将他们的主要首领全部杀死，夺回汉朝的百姓，获得很多牲畜财物。
遂绳索相悬，上通天山，大破乌桓，悉斩其渠帅，还得汉民，获其畜生财物。
They connected with ropes and hung each other up, going straight across the Tianshan Mountains, defeating the Wuhhuan army, killing all their main leaders, and taking back the Han people, obtaining a lot of livestock and money.
