《太平广记·卷四百二十三·龙六》
到长庆年初，一个住在这个寺院里的人，有一天仰卧在门外，见有一个东西从窗出来，轻飘飘的，像一朵云，飞出寺院，向渭水飞去。
至长庆初，其寺居人有偃于外门者，见一物从西轩直出，飘飘然若升云状，飞驰出寺，望谓水而去。
Early in the Changqing period, someone who lived in this monastery saw something coming out of the window when he was lying on his back outside the door one day. It floated lightly like a cloud, flew out of the monastery, and flew towards the Wei River.
