What is pork belly? Pig elbow is the meat there.

The back is called tenderloin (all thin), the abdomen is called Wuhua (one layer is white and the other is red), and the legs are called elbows. A small piece of lean meat scraped from the ribs is called tenderloin, the diagonal is very thin, and the shoulder position is called deltoid muscle. There are also pig heads, pig ears and tail, front legs and hind legs.

However, no matter how subdivided, pigs only have pork. No matter how fat a pig is, it can't grow beef.
