Why Does Reed Ash Stop the Flood?
Banking reed ash against the flood brings an ordinary plant material into cosmic repair and returns attention from sky to land.
Narrative context
Huainanzi: Lanming preserves the core acts of the sky-repair account: refining five-coloured stones, cutting the legs of a giant turtle, killing a black dragon and banking reed ash against the waters. Later retellings connect Gonggong, Mount Buzhou and human creation into one timeline.
Evidence
The repair passage ends by banking reed ash against overflowing waters. The verb indicates accumulation, and the action concerns flood control on earth rather than the patching of heaven.

Comparative reading
The term must first be read in its original sentence and period. Modern analytical language can assist comparison but cannot replace the source’s vocabulary.
Stones repair the sky, turtle legs support the four extremities, the black dragon represents danger in Jizhou, and reed ash addresses floodwater. The four acts restore both cosmic structure and the inhabited world.
