Nothing

Lots of sometimes mildly bloody Marital Arts Violence which often includes weaponry. Film opens with a funeral pire, several wrapped bodies are burning. Hundreds of dead soldiers and civlians , including kids, shown on a battlefield (non gory). Soldiers with guns and bayonets aggressively interact with civilians. Many people are shot Or sliced and killed during the movie, sometimes in mass, a little blood is shown via bullet holes! Small splatters or trickles from mouth. A child is run over by a horse, blood pours from her mouth and parents mourn over her body for a long time. A character is viciously attacked and run through with blades, not ultra gory but bloody. 2 men are graphically impaled on swords while fighting. Bombs blow up a building. A character is crushed and coughs up tons of blood.

There is one disturbing scene near the beginning where a Chinese soldier riding a horse tumbles with the horse down a flight of stairs. The horse rolls down the stairs and does not appear to be CGI. There are quite a few scenes of what appear to be real horses falling and crashing.

Some mild name-calling such as "bastards".

A woman is held underwater in an attempt to drown her. Many of the fight scenes are intense and dramatic, especially those with weapons. Scenes where kids are in danger or are harmed could freak out younger viewers. The movie is about warlords vs. Shaolin, so there are a lot of civilian as well as monk/soldier casualties
