Taiwan locates in the central position of the East Asia island arcs. Taichung has three major transportation portals: Taichung Port, Taichung International Airport, and Taiwan High Speed Rail Taichung Station, making it a city that people can access by sea and air. Its geographical advantage is that it can reach major Asian cities such as Beijing, Shanghai, Tokyo, Seoul, Manila, Ho Chi Minh City, and Singapore within four hours through Taichung International Airport. In the maritime part, the Free Trade Zone of Taichung Port is adjacent to the processing export zone, industrial zone, science park, and other industrial zones, where upstream and downstream industries gather, and their operation performance ranks first in the country. Taiwan's northern, central, and southern parts form a daily life circle, and Taipei or Kaohsiung can be reached within one hour through the Taiwan High-Speed Rail Taichung Station, making it the second-largest station in passenger traffic in and out of the country
