I know this might be a stupid câu hỏi but I can't never figure it out, why don't ma cà rồng have tim, trái tim beats? Like I know their hearts beat but like how come bạn can't hear it?

Depends on what lore bạn follow. If you're going with the 'all ma cà rồng do not have heartbeats' it's proooobably because they're dead.
However, if bạn ask me, they just have exceptionally strong hearts, so they don't have to beat fast hoặc hard to máy bơm the blood around the body. (Sorry, I'm a bit of a science nut, I like to make things sound possible. ma cà rồng included.)

Well, one obvious reason is that they're dead.

i have my own theory, i think its cuz they have a heartbeat but its just quiet because it doesn't need to work as much to keep them alive. also maybe only other ma cà rồng can hear it and just not human?, i don't know but i'd just go with what bạn wanna believe in. i mean with all the vampire stuff everyone pretty much has their own version

because they are nondeath

Actually, their hearts do not beat. ma cà rồng are dead. They are a spirit in a dead body, which is why they sometimes are called "damned". Since they are dead, their tim, trái tim does not beat and the blood they drink is the only thing that can provide them the energy they need.

Don't worry, this isn't a stupid câu hỏi ;)! I had a whole philosophy class on ma cà rồng last semester, it was awesome ;) and it helped me now so much about vampires!

bạn talk like bạn met a vampire hoặc something. It all depends on whose vampire bạn are talking about, if they are the version that aren't dead then their tim, trái tim beats, if they are the version that are dead, then their hearts must likely don't beat. One funny câu hỏi though, what do bạn mean hear it, who's hearing it, so far as i know a human can't even hear another human's heartbeat unless with a stethoscope, hoặc maybe leaning in close
