The Matchmaker comically gets her butt burned by a couple of hot stones she accidently sits on.
Minimal blood is shown.
At one point we see a bunch of bodies in a snowy field, with some pretty greusome depictions such as bodies without hands, including a close-up on a face-down body with multiple arrows sticking out of it.
Some war violence, but nothing graphic
When her horse Khan laughs at her attempts to impersonate manly behavior and speech, Mulan petulantly flings one of her shoes at his head.

There's some mild horseplay and jostling between the men in the bathing sequence, and during the "A Girl Worth Fighting For" musical sequence.
The silhouetted bodies of several dead soldiers and war horses among ruined carts and caissons, all partially covered in snow, are shown at a distance in an extremely brief shot.
Shang takes an arrow to the armor on his shoulder, which knocks him off his horse, but doesn't manage to draw any blood.
Off-camera, someone dope slaps Yao for asking whether his dress (concubine disguise) makes him look fat.
