  This paper introduces an innovative framework for understanding the world,
termed the "Three Realms and Six Layers Model". Based on the concept of scale,
the world is divided into three realms, each encompassing six layers, with a
ten-thousand-fold difference in scale between adjacent layers. This unique
division reveals the variations in laws at different levels and the fundamental
changes in laws when transitioning between realms. The model offers a new
perspective for addressing interdisciplinary issues, especially in
understanding the behavior of large-scale systems and their connection to
microscopic phenomena. In summary, the "Three Realms and Six Layers Model"
provides a novel tool for comprehending the diversity and complexity of the
universe.
