Coherent principles and research can be used to speculate and make accurate predictions from the past. System principle • Think of prediction objects and various events as a system, conduct comprehensive investigation and research, comprehensively analyze problems, prevent one￾sidedness, and improve the scientific nature of prediction. Seeking truth from principle • In the process of forecasting, it is necessary to proceed from objective facts, respect historical data, and analyze future trends with reference to past accident development laws in order to obtain more accurate prediction results. Mass observation principle • Forecasting is based on a large amount of data analysis, from which to find out the general rules, to avoid partiality
