				        	Based on the knowledge background of ancient Chinese technology, including odd-even numbers to yin-yang, diurnal (day-night) cycle and annual (four seasons) cycle, changes of solar light manifestation and land surface temperature, a method of deduction and verification for Hetu (《河图》) and Luoshu (《洛书》) was proposed in this paper. To ensure the scientific rigor of research, the equivalent numbers to yin-yang were defined, and the diurnal as well as annual cycle models under coordinate system were constructed. On this basis, the Hetu and the Luoshu were derived by means of the variation regulations of solar irradiance and surface atmospheric temperature within one day and one year, which provided a solid foundation for the correct comprehension and application of Hetu and Luoshu. In addition, it was proved that Hetu and Luoshu could be derived from each other by using the equivalent numbers to yin-yang, which means the feature of unity. Multiple equivalent numerical forms for Hetu and Luoshu were presented.
