helmet, head piece
兜 centers on protective headgear: a helmet or head piece worn for defense.
兜 is thought to depict a helmet covering the head, with the upper part representing the helmet and the lower 儿 suggesting a person. The exact historical development is uncertain.
The top part looks like a protective shell with 白 inside, and the bottom 儿 resembles a person. Imagine a warrior with a white-crested helmet covering their head.
For トウ, picture a tough helmet taking a blow: tough -> トウ, and the helmet protects the head.
