This is a fictitious story in which the Viet, the Koreans, the Mongols, the Xiongnu, the Khitan, and the Tibetans all coexist in peace with China at the same time. It is a Golden Era of peace and prosperity. In this setting, you will build the city of Songzhou, the ultimate "elite" city. I believe that this city will contain the highest number of Heavenly Compounds possible without compromising the stability of the city. Perfect Feng Shui is possible. A .txt document is available with spoilers in the "Completed Cities" download section of the Emperor website; this is in a file labeled "Golden Songzhou."
