Chine, Japan, Korea

The rule of thumb for the Chinese Grid was that capital city design should be laid in a square grid measuring 9 by 9 li (about 4.5 km) per side with three gates on each of the city walls. Along with these regulations there should be 9 streets and 9 avenues. The layout corresponded as follows: The palace is placed in the center of the city. The Ancestral temple to the left of it and the temple to the deities to the right. Office buildings are to be placed in front and the markets to the back. Koreans and the Japanese were influenced by Chinese urban form and adopted the grid around 700 AD.
