The development of veterinary medicine is directly related to animal health and human well-being. Animals are not only friends of humans, but also an indispensable part of the ecological chain. As guardians of animal health, the career development of veterinarians plays a crucial role in ensuring animal health, controlling animal diseases, and maintaining ecological balance. The development level of veterinary medicine directly affects the effectiveness of animal disease prevention and control, which in turn relates to the healthy development of animal husbandry, food safety, and public health safety. At the same time, with the continuous progress of society and the increasing awareness of animal welfare among people, the requirements for the veterinary profession are also becoming higher and higher. By conducting in-depth research on the current situation, problems, and development trends of the veterinary profession, strong support can be provided for the standardized development, talent cultivation, technological innovation, and other aspects of the veterinary industry. This not only helps to enhance the overall image and status of the veterinary industry, but also promotes its sustainable development. Veterinarians are not only guardians of animal health, but also guarantors of human health. Therefore, strengthening the development of veterinary medicine and veterinary professional research not only helps to improve the overall level of the veterinary industry, but also makes positive contributions to maintaining human health and promoting social harmony and stability. This book will explore the development and research of veterinary medicine from six aspects: the development of modern veterinary medicine in China (1904-1949), the administrative system of veterinary medicine in China, the grassroots veterinary service system, ethical considerations in veterinary public health, and the study of the socialized service system of veterinary medicine - taking Hohhot as an example and the vocational education model of veterinary medicine under the new veterinary system, in order to provide reference for the development of veterinary medicine in China.
