Where did the meat-to-meat noise come from in action movies? expert opinion/advice

Now most movies are dubbed in the later stage.

The traditional way is true. Find a few employees to do it in a specific dubbing room. There are all kinds of props that will appear in the movie, and of course there is meat. Then sound according to the progress of the film.

The latter is widely used now, and computer synthesis makes the sound more textured, but it is also a bit unreal. For example, the sound of drawing a gun in CS will also appear in movies, hehe.
