Sun and moon like a weaving shuttle — time darts past.
Literal meaning
sun (日) — moon (月) — like (如) — shuttle (梭)
Origin
An image from classical poetry: a weaving shuttle (梭) crosses a loom so quickly the eye can barely follow it; the sun and moon, in their endless alternation, move with the same darting speed. Often paired with 光阴似箭.
