Chenyun

Chunyun (traditional Chinese: 春運; simplified Chinese: 春运; pinyin: Chūnyùn), also referred to as the Spring Festival travel season or the Chunyun period, is a period of travel in China with extremely high traffic load around the time of the Chinese New Year. The period usually begins 15 days before the Lunar New Year's Day and lasts for around 40 days. The number of passenger journeys during the Chunyun period has exceeded the population of China, hitting over 2 billion in 2008. It has been called the largest annual human migration in the world. Rail transport experiences the biggest challenge during the period, and myriad social problems have emerged.
