Because of the financial crisis, the southern coastal cities have been greatly affected, while the central economy has good expectations and great development potential.
Besides, I think the most promising industries are energy industry and communication industry. For example, the recent increase in electricity prices is an example. Moreover, there has been a "gas shortage" phenomenon in many cities. If we can master energy, we can master the economic lifeline of the country. With the development of society and the popularization of 3G technology, the potential of communication industry is immeasurable.
