The ancient name of a veterinarian.

The earliest records of veterinarians can be found in Zhou Li. Veterinarians include "treating animal diseases (internal medicine)" and "treating animal selection (surgery)", as well as "Wu Ma" who specializes in treating horse diseases, and even "Fun Ma" who is good for horse health care. In Xia, Shang and Zhou dynasties, the greatest achievement of veterinary medicine was the emergence of castration. In Zhou Li, "attacking foal" and "attacking specialty" refer to castrating stallions.
