An estimated 50 million of those were railway trips, which would represent a 10 percent increase from the same period last year, China Railway Corp said.

Stations in Beijing, Shanghai, Guangzhou, Wuhan, Shenzhen, Hangzhou, Nanjing, Chengdu and Zhengzhou were among the most crowded this year, based on ticket sales, the company said, adding that the travel peak appeared on Saturday, when 13.7 million trips were made.
