Administratively, the capital was divided into 21 districts: six of merchants, which provided the Qi state's trade revenue, and fifteen of attendants, which provided the core of the Qi army. Similarly, the population outside the capital was organised: 30 households were formed into one village, 10 villages as one troop, 10 troops as one district, 3 districts as one county, and counties grouped into five regions. Administrators were appointed at every level, with the regional administrators reporting on their jurisdictions to the Duke every year.
