The main ingredient in authentic borscht is supposed to be beets, and the meat is just a supporting role, so it doesn't really matter what kind of meat it is, it's usually beef, and it's not wrong to use pork.

The current borscht, which was brought in by Russians exiled in Shanghai after the October Revolution, has been modified in the Chinese style, using cabbage, potatoes, tomatoes, and other main ingredients, and in some cases even adding vermicelli.
