Train tickets for the Spring Festival travel rush go on sale on Jan. 3, 2018. China's transport system is often put to the test during the annual travel rush around the Spring Festival. The period is called "chunyun," which literally means "Spring Festival transport." During Spring Festival, which falls on Feb. 15 this year, hundreds of millions of Chinese will go back to their hometowns to celebrate the most important holiday of the year with their families.
