The “move away” policy or how to battling pollution in china

Big cities face heavy environmental protection pressure. For instance, Beijing has a daily environmental index and the government also implements an annual “blue sky” plan. And environmental protection departments are especially under heavy pressure to fulfill their quota of emission cuts every year.
From this we can see that the government is very strict about emission reduction.
But how are we solving our environmental problems in large and medium-sized cities? The common practice is to move polluting enterprises such as coal-fired power and steel plants away from the cities to the remote areas.
