Background & setting
The Shanhaijing describes related figures called Zhuyin and Zhulong in its northern regions. Human face, serpentine body and immense scale give natural processes a bodily presence. The passages are mythic descriptions, not ancient measurements of a real species.
The story
When the being looks out, it is day; when its eyes close, it is night. Blowing and breathing are linked with winter, summer and wind. The creature needs neither ordinary food nor ordinary rest: what would be a small bodily movement for a person becomes the condition of the whole world.
This differs from stories in which a deity drives a sun across the sky. The alternation itself is embodied. Reading Zhulong alongside Xihe and Changxi reveals several ways of imagining the heavens, without needing to force them into a single physical explanation.
How to read it
The enormous body makes time and weather visible. It is a striking example of myth giving form to processes too large to grasp at once.
