Why should tourism consider 1 hour and 2-hour traffic circle?

Because "1 hour 2-hour traffic circle" is the most effective range for the exchange of elements between central cities and surrounding areas. Refers to the formation of the main city as the core, within one hour of traffic access, with obvious agglomeration effect and competitive advantage. For example, the Yangtze River Delta economic circle is a place with Shanghai as the center and traffic within an hour; Chongqing economic circle is a place with Chongqing as the center and the traffic can be reached within one hour.
