How is Chinese folk regions are different from the five major regions?

Chinese folk regions are smaller, culturally distinct areas within the broader framework of the five major geographic regions—North, South, East, West, and Central China. While the five major regions are based on geography and administrative divisions, folk regions reflect local customs, dialects, traditions, and lifestyles that can vary significantly even within a single major region. These folk regions often highlight ethnic diversity, historical influences, and specific cultural practices that are not necessarily tied to geographical boundaries. As such, they provide a more nuanced understanding of China's rich cultural tapestry.
