My name is Feng. They said this was Dadu, the heart of the empire. I will stay here for the rest of my life - as a prince. "How big is the empire and how big is the capital?" I once asked them. "South of the Holy Mountain and north of Long Lake is the empire." This is the answer I got, but what is Long Lake and where is the Holy Mountain? I still remember my brother's chuckle: "Everything you can see is the king's land. Mountains, rivers, and all living things." That look was filled with pride and sadness.
