三通
In Taiwan, spring travel is also a major event. The majority of transportation in western Taiwan is in a north–south direction: long-distance travel between urbanized north and hometowns in the rural south. Transportation in eastern Taiwan and that between Taiwan and its islands is less convenient. Cross-strait flights between Taiwan and mainland China began in 2003 as part of Three Links, mostly for "Taiwanese businessmen" to return to Taiwan for the new year.
