What's the difference between traditional Cantonese crispy roasted meat, raw roasted meat and cooked roasted meat?

In fact, the biggest difference between the two is the flavor. Raw roast emphasizes the meat flavor of pork itself, which tastes delicious, while cooked roast is cooked before burning, which leads to excessive loss of meat flavor. This kind of pork belly has only crispy skin, and the meat tastes more like slag.
