《太平广记·卷三百九十六·雨（风》
不一会儿，出现了云雾使大家互相看不见，又隐隐约约听到好象在远处打雷的声音，时间不大有一条彩龙和一只红色的天鹅一起飞走了。
须臾，云雾不相见，又闻隐隐如远雷之响。俄有一彩龙，与赤鹄飞去。
After a while, clouds and mists appeared, making everyone invisible to each other, and vaguely heard sounds like thunder in the distance. Not long after, a colorful dragon and a red swan flew away together.
