In the neighborhood of Wu Tzu-tien (a tree named for the only female emperor in Chinese history), there is a small stretch of Taiwan sassafras growing. The supple leaves of this plant are a favorite food for Papilio xuthus butterflies, and if your luck is running good you'll be able to see these two protected species, one plant, one animal, side-by-side.
在武則天神木附近，長有一小片台灣樹，這種樹的嫩葉，正是寬尾鳳蝶愛吃的美食，若是運氣好的話，就可看到這兩種保育類的動、植物。
