Chunyun, or special transport arrangements for the Spring Festival travel rush, is considered the most spectacular annual human migration on Earth, the 40-day period when Chinese head home to celebrate the Spring Festival. This year's festival falls on February 12. The official Chunyun begins on January 27 and will end on March 8. With sporadic new outbreaks of COVID-19 in China, officials have warned of the danger of travelling. The Chinese government has advised its people to stay put for the Spring Festival, but at the same time, the government also warned against arbitrarily increasing the level of control. Join CGTN reporter Lu Sirui at the Guangzhou Railway Station to see how Chunyun this year is different from previous years and what measures are taken to ensure people have a safe journey home.
