Some of the violence is kind of faked but some are realistic and very graphi.
Towards the beginning of the film, we see a man get his hand chopped off with a cleaver on screen, and a very fake stump of a hand afterwards. It is also implied that his head is chopped off too.
A woman throws another woman down a flight of stairs after hitting her with a chair. This kills her.
A woman pushes a giant flower urn from a balcony and it crushes two people. We see their bodies later.
A woman shoots a man in the face, and we see blood.
There are multiple scenes in which we see dismembered hands, heads, or headless bodies.
Though this movie is incredibly graphic, most of the violence is very fake.
