ABSTRACT
This chapter demonstrates that the layout design of the Ye city influenced all other East Asian countries. Specifically, Chinese, Japanese, North Korean, South Korea, and Vietnamese peoples constructed their capital cities in line with the “heaven–humanity” interaction. Hence, these capitals have common characteristics such as left–right symmetry around the central axis, palace city–barbican concentricity, and checkerboard-shaped street distribution. These characteristics constitute the so-called capital layout lineage of East Asian countries in the medieval period.
