Spring travel

Traditionally, families gather together during the Chinese New Year. In modern China, migrant workers in China travel home to have reunion dinners with their families on Chinese New Year's Eve. Owing to a large number of interprovincial travellers, special arrangements were made by railways, buses and airlines starting from 15 days before the New Year's Day. This 40-day period is called chunyun, and is known as the world's largest annual migration. More interurban trips are taken in China in this period than the total population of China.

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 China began in 2003 as part of Three Links, mostly for "Taiwanese businessmen" to return to Taiwan for the new year.
