Abstract: In recent years, a large number of new archaeological discoveries and research results show that, influenced by geographical location and climate change from MIS3 to MIS2, both local and new populations moving into North China continued to migrate and disperse. The simple core-flake technology that existed for a long time in North China, through constant exchange and mixing with incoming populations, developed into the boat-shape micro-blade core technology. Mousterian and blade technologies from western Eurasia also had an impact on North China. During MIS3, external influence was only seen in the eastward movement of populations from high latitudes. To cope with the environmental pressure of MIS2, the blade and wedge-shape micro-blade core technology from North and Northeast Asia spread southwards. However local people in North China chose to adapt the boat-shape micro-blade core technology which was fit for high mobility, survival and further development
