China's largest internet search engine Baidu – often referred to as the Google of the East - has launched a heat map which captures the largest global seasonal migration on earth.

Chinese officials estimate that some 3.65 billion journeys will be made over the 40-day travel period associated with the Chinese New Year festival.

The interactive map is updated every four to eight hours.
