The guide stated that 149 million domestic trips will be made by Chinese tourists over the holiday period from April 29 to May 1, achieving the tourism revenue of $13.9 billion.

Cities including Beijing, Qinhuangdao, Dalian, Harbin, Shanghai, Sanya and Hangzhou are the most popular tourist destinations, according to the guide.
