"Chunyun", the world's largest annual human migration takes place every Chinese New Year. This cultural phenomenon consists of over three billion passenger-journeys, largely for the purpose of spending treasured time with family. It usually begins 15 days before Lunar New Year's Day and lasts for around 40 days.
Of the phenomenal 3 billion journeys, 2.43 billion trips will be made by automobile, 440 million by rail, 79 million by air and 45 million by sea. Already boasting the world's largest rail network, China has built 8,489 kilometers (about 5,275 miles) of new railway lines in 2019, including 5,474 kilometers of high-speed rail.
The documentary was produced by Jonathan Bregel, and additional information about it can be found on Directors Cut.
