Examples in ancient books of folk becoming immortal by eating gui are too many to mention, and on a rubbing of an Eastern Han dynasty carved tile from Sichuan, we actually see the moon depicted as a disc on the belly of a celestial immortal; within the disc are a toad and a gui tree.
古書裡食桂成仙的例子不勝枚舉。在一張東漢時四川畫像磚中，我們更可以看到，月亮原來是天上羽人腹部的圓輪，其中還有一隻蟾蜍和一株桂樹。
