Shenyang's metropolitan area traditionally consisted of the 5 small inner urban districts, surrounded by 4 larger outer suburban districts, and accompanied by 4 rural counties on the north and west sides. In general, agriculture, animal husbandry and agricultural product processing dominate northeastern Shenyang; eastern Shenyang is an automotive parts hub; southern Shenyang is a high-tech industrial base; and western Shenyang is home to heavy machinery manufacturing. The city center specialises in retail and financial services.[1]
