《太平广记·卷七十五·道术五》
有人请他饮酒，如果他满意，就用纸剪二三十枚蝴蝶，用气一吹，这些蝴蝶就成排地飞，这样过了很长时间，他就用手指去把它们回收回来，不一会儿都收在手上。
或人召饮，若合意，则索纸剪蛱蝶二三十枚，以气吹之，成列而飞，如此累刻，以指收之，俄皆在手。
Some people invited him to drink, if he was satisfied, he would cut twenty or thirty butterflies, blew into the air, these butterflies flew in lines, after a long time, he would collect them with his fingers, and after a while, they were all in his hands.
