It is an important central city in eastern China, an important scientific research and education base in China, and a comprehensive transportation hub approved by the State Council.
Nanjing is located in the east of China, the lower reaches of the Yangtze River and coastal waters. It is the seat of China East Theater Command, an important gateway city for the development of the central and western regions driven by the Yangtze River Delta radiation planned by the State Council, and an important node city for the strategic intersection of the eastern coastal economic belt and the Yangtze River economic belt. ?
Historically, Nanjing has benefited and suffered from its unique geographical location and extraordinary geomantic scenery. In the past, Nanjing suffered many military disasters, but it also rebuilt its prosperity from the ruins many times.
When China was occupied by foreign countries and the Han nationality was about to suffer extinction, the Han nationality usually chose Nanjing to recuperate and aspire to the northern expedition and restore China.
