During the traditional Chinese New Year holiday from Feb 7-13, hundreds of millions of people travelled across the nation, while many chose to travel overseas to spend the most important holiday, traditionally a time for family reunion. Here with the help of data we take a look at some of the major changes during this year's weeklong holiday.

1. Passenger trips reach 400 million

Passenger trips reached 400 million during the seven-day holiday from Feb 7 to 13, up 6.7 percent from 2015, Ministry of Transport data showed. The holiday-goers travelled by train, road, air and even by car pooling. Chinese ride-hailing apps like Didi offered help in the festival travel rush for the first time. Car pool trips arranged via Didi were equivalent to an extra 1,500 high-speed trains with eight carriages.
