Spring Festival travel rush dates back to ancient China but only for rich and powerful
Epic New Year journeys by land and sea 2,000 years ago used to take a month to complete; then nation began developing transport systems

The world’s largest human migration, China’s Spring Festival travel rush, could date back more than 2,000 years and reflects the history and development of China’s transport networks.
This year’s Spring Festival rush, or chunyun, takes place from February 2 to March 13, and is expected to produce a total of 9.5 billion passenger trips.
The chunyun is believed to first appear along with the invention of the term guo nian, or spending the New Year, in the Zhou dynasty (1046–256).
The New Year, which is also known as the Spring Festival, was celebrated with worshipping rituals to pray for a good harvest in the following year.

The tradition of family reunion during the period was also established then to demonstrate the Confucian value of filial piety.
