Wang Xintong, 8, woke up at 5am on the morning on Jan 13, prepared to embark on a long trip back home with her parents. Jan 13 was the first day of the 2017 Spring Festival travel rush.

A bus from Fuqing in Fujian province took the family to Fuzhou Railway Station, where they began the 26-hour train ride to Dazhou, Sichuan province on special train K4186 for migrant workers. They transferred to train K788 and arrived at Chongqing late on Jan 14. After spending the night in Chongqing's Liangping district, the family began the last leg of their journey via car the next morning, finally arriving at their home in Hongqi Village. The trip covered more than 2,000 kilometers and took over 40 hours.
