Abstract: Strive for 70 years, strive for a new era. Under the leadership of the Communist Party of China, China's public health adheres to the System of Socialism with Chinese Characteristics, and always implements the policy of putting prevention first. Since the founding of the People's Republic of China, after the reform and opening up, a public health system with a combination of epidemic prevention and disease prevention with Chinese characteristics has been established, and a public health undertaking with Chinese characteristics has been created. Especially since the 18th National Congress of the Communist Party of China, China's public health has spurred the slogan of "Implementing a Healthy China Strategy" in the new era, and fully promoted the "the Plan for Health China 2030" to lay a solid foundation for the Chinese dream of realizing the great rejuvenation of the Chinese nation.
