The violence in this film is strong but doesn't focus just on the blood. It has its bloody moments but not like something in a Tarantino film. The violence includes severe shootouts and knife fighting to brutal Martial Arts violence. The most blood is shown in the knive fights and some in the shootouts.
The most severe scenes of violence are when the main character stabbed a man in the genitals and blood comes pouring and soaking out and when he strangled a man to death onscreen with a belt. His face slowly turns purple and eventually dying.
