Opening with the Chengdu-Chongqing railway, the first railway built after the founding of the People's Republic of China, this episode discusses how the evolution and upgrading of "China Speed" have contributed to the grand strategy of regional coordinated development. It highlights how the connectivity of roads and rail networks has promoted the formation of large industrial and innovation clusters, and how technological innovation, industrial upgrading and rapid inter-city connectivity are narrowing the urban-rural gap and achieving a more balanced allocation of resources. At the same time, China's efforts to promote international logistics corridors are further expanding both domestic and international openness and fostering the dual circulation of domestic and international markets. The path of Chinese modernization, paved by "China Speed", is leading to a bright and shared future for humanity.
