Authorities in China expect 3.65 billion journeys during the Chinese New Year travel period. The number of trips - almost three times the population of China - include intercity flights, trains and local bus rides to villages during China's most important holiday, which is also known as Spring Festival. Each year, it represents the world's largest seasonal migration of people as families reunite.

Lian Weiliang, vice-chairman of the National Development and Reform Commission, said authorities expected 200 million more journeys than in 2013 but warned that snow and bad weather could hamper the mass migration.

Baidu, China's largest search engine, has created a visualisation of the most popular travel routes, based on user location data.

The Year of the Horse starts on 31 January.
