1. Core Concept (核心概念)
Yu Tu (玉兔)—the “Jade Rabbit”—is the immortal hare who resides on the moon, forever pounding the elixir of immortality (仙药) with a mortar and pestle beneath the cassia tree. One of the most beloved figures in Chinese folklore, the Moon Rabbit embodies selfless devotion, longevity, and the soothing light of the full moon.
The rabbit’s association with the moon likely began with the moon’s surface markings: ancient Chinese sky-watchers saw not a “man in the moon” but a rabbit crouching by a tree—an image recorded as early as the Warring States period in the Chu Ci (楚辞, Songs of Chu).
2. The Legend of Self-Sacrifice (舍身传说)
The most moving origin tale tells of three animals—a fox, a monkey, and a rabbit—who encountered the Buddha (or the immortal Jade Emperor, in some versions) disguised as a hungry old beggar:
- The fox caught a fish for him.
- The monkey gathered fruit.
- The rabbit, able to find nothing but grass, leapt into the fire, offering its own body as food.
Touched by the rabbit’s sacrifice, the deity resurrected it and placed it on the moon, where it became the immortal Jade Rabbit. The story teaches that sincere selflessness outweighs material offerings—a moral cherished during the moon-gazing season.
3. Companion of Chang’e (嫦娥的伴侣)
In the most widespread version of the mythology, the Moon Rabbit is the loyal companion of Chang’e (嫦娥), the moon goddess:
- Chang’e drank the elixir of immortality and floated to the moon, where she lives in the Guanghan Palace (广寒宫)—the “Cold Palace of Vast Cold.”
- Her only company is the Jade Rabbit, who pounds the elixir day and night in the hope of one day preparing enough for Chang’e to return to Earth—or to ease her eternal loneliness.
- Nearby stands the cassia tree (桂树), endlessly chopped by the woodcutter Wu Gang; the rabbit’s pounding and Wu Gang’s chopping are twin symbols of ceaseless devotion.
4. The Rabbit in the Mid-Autumn Festival (中秋的兔儿爷)
The Moon Rabbit takes tangible form every Mid-Autumn Festival, most famously in Beijing as Tu’er Ye (兔儿爷), the “Rabbit God”:
- Clay figurines of the rabbit dressed as a general or official are sold at temple fairs; children set them on home altars and later smash them, a custom believed to dispel misfortune.
- Rabbit-shaped pastries and mooncake molds shaped like the Jade Rabbit appear across China.
- In folklore, the rabbit is said to descend during the festival to bless children and heal the sick, which is why old Beijing households displayed Tu’er Ye figurines facing the courtyard.
The full moon of the 15th day of the eighth lunar month is considered the moment when the rabbit’s image on the lunar surface is clearest and most complete—the night’s “reunion” theme reinforced by the rabbit’s own story of loyalty across separation.
5. Across East Asia (东亚的月兔)
The Moon Rabbit’s fame extends far beyond China, carried along the Silk Road of ideas:
| Region | Name | Distinctive Detail |
|---|---|---|
| China | 玉兔 (Yu Tu) | Pounds the elixir of immortality for Chang’e |
| Japan | 月の兎 (Tsuki no Usagi) | Pounds mochi (rice cakes) on the moon |
| Korea | 달토끼 (Dal Tokki) | Pounds the elixir of life under the laurel tree |
| Vietnam | Thỏ Ngọc | Accompanies Chú Cuội, the man in the moon |
The 1969 Apollo 11 mission added a modern epilogue: before stepping onto the moon, Houston jokingly told the astronauts to “watch for a lovely girl and a big rabbit.” Astronaut Michael Collins later cabled Beijing’s planetarium: “We looked for the Jade Rabbit, but did not find him.”
6. Symbolism Summary (象征意义)

- Longevity & immortality: as elixir-pounder of the immortals
- Loyal companionship: never abandoning the lonely Chang’e
