《太平广记·卷四百五十·狐四》
徐安在这天晚上，把妻子关在别的屋里，就假扮成女人的样子，袖里藏着短剑，骑着旧笼子等在那里，到二更时，忽然从窗户飞出去，一直飞到一个山岭上，才到了相会的地方。
安是夕，闭妇于他室，乃诈为女子妆饰，袖短剑，骑故笼以待之。至二更，忽从窗而出。径入一山岭，乃至会所。
On that night, Xu An locked his wife in another room and disguised himself as a woman. Hiding a dagger in his sleeve, he waited there on the old cage. At the second watch, he suddenly flew out of the window and flew to a mountain ridge where he found the rendezvous.
