The Qing-dynasty book Liaozhai Zhi Yi Wai Ji contains this passage: "Winter worm summer grass is aptly named / In change and birth there is but one qi / One thing can indeed be both animal and plant / The world contains more wonders than we can understand."
是昆蟲還是植物？《聊齋誌異外集》中有此一說：冬蟲夏草名副實，變化生成一氣通。一物竟能兼動植，世間物理信難窮。
