The first high-speed train of the morning departs Shanghai Hongqiao Station, its destination screen flashing between Suzhou (23 minutes), Hangzhou (45 minutes), and Nanjing (60 minutes). This seamless connectivity symbolizes the economic and cultural integration transforming China's most developed region - the Shanghai-centered Yangtze River Delta (YRD) megacity cluster.

- 38% of total foreign trade volume
- Home to 3 of world's top 10 container ports
