马革裹尸 [- - ɡuǒ shī]be wrapped in a horse's hide after death — die on the battlefield; be killed in battlefield; die in the last ditch; fall in battle; lay down one's life on the battlefield; wrap the corpse in horse skin — not to return alive from the battle:
•¶ 青山处处埋忠骨， 何必马革裹尸还? There are green hills everywhere to bury loyal bones; why wrap the corpse in horse hide and bring it back?
