Physical scenarios, universal exchange across all industries—just like the pizza exchange approach back then—using equivalent material consensus value to trade. Everything naturally circulates. After all, people earn money and accumulate wealth to ensure worry-free clothing, food, housing, and transportation. In this intelligent era, with homogeneous group procurement and homogeneous distribution, if there's no consensus, things wouldn't appear under the same sky. Achieving internal circulation means using exchange to solve real-world material needs. On top of spiritual civilization and moral values, consciously and voluntarily exchange gratitude feedback, adding an extra dimension to life—a consensus of huddling together for warmth, co-building and co-sharing mutual material life security. No matter what we play, it's ultimately for worry-free food and clothing, and security in old age.......... Welcome to discussion.
