A country like China with such a tremendous population needs meticulous urban planning. In the past few decades, the country's economy has been booming. However, its cities are still having difficulties keeping up.

In modern mega cities such as Beijing, old buildings have been torn down in exchange for new skyscrapers to hold millions of residents. Some cites are over-saturated, others are losing its residents. 

In the Northeast provinces, over 200,000 people move to first-tier cities for better job opportunities each year as old industrial sites diminish. 

The 13th five-year-plan that came out this year is set to optimize the country's city planning. The government has decided to transform the industrial cities into greener and more sustainable high-tech based ones.

19 city clusters will be established to boost the less developed cities within each radius. And to improve regional connectivity, China is set to cover 80 percent of its cities with railway lines. The total length will reach 150 thousand kilometers by 2020.
