Lunar New Year
It is the first Lunar New Year celebration since China's communist leadership lifted the country's strict measures to slow the spread of the coronavirus.
The Lunar New Year is a huge holiday in China, but also in other Asian countries like Korea and Vietnam. More than one billion people will be celebrating the event, which begins on January 22. For most, it's the Year of the Rabbit but in Vietnam, people will mark the Year of the Cat.
China expects the total number of passenger trips made by travellers by road, rail, water and flight during the upcoming Lunar New Year to reach 2.1 billion this year, double from last year's 1.05 billion during the same period.
