In Yang Jianshun's view, in the prevention and control process, all localities must adhere to the "scientific and orderly prevention and control according to law", adopt reasonable ways and methods, and adhere to the correct value orientation, in order to ensure effective prevention and control and win the battle against the epidemic.

Yang Jianshun said that reasonable and legal prevention and control should emphasize respect for the regularity of the fight against the epidemic, pay attention to the effectiveness of the fight against the epidemic,

and reflect the characteristics of coordination and humanistic care. To take relevant prevention and control measures, we must adhere to the principle of proportionality and ensure effective prevention and control.

Those who adopt isolation measures and return measures should do a good job in supporting work such as caring, helping and guaranteeing, refrain from stereotypical, indifferent, arbitrary and domineering practices,

establish and improve a social governance pattern of co-construction and co-governance, fully mobilize the enthusiasm of all parties, work together, and consolidate the joint prevention and control response mechanism.

In addition, Yang Jianshun suggested that the state establish an emergency management system based on unified leadership, comprehensive coordination, classified management, hierarchical responsibility,

and territorial management. Under this system, all localities and fields should be fully endowed with the power to flexibly respond to public health emergencies according to the actual situation,

and on the basis of further improving the rules of empowerment and procedures for the use of power, To maximize the use of scientific and rational prevention and control measures, adhere to and practice the principles of "early detection,

early reporting, early isolation, early diagnosis and early treatment", so as to eliminate risk factors to the greatest extent, and achieve the most timely, reasonable and effective scientific and rational prevention and control.
