Seeing red

Meanwhile, according to the China Tourism Academy, 2017 saw more than 800 million tourist visits to 109 classic red tourism sites in 18 Chinese cities, an increase of 13.3 percent over 2016. And the average age of the tourists was 35.

According to online travel agency Ctrip, from January to May, 32 percent of their Chinese customers visiting red tourism sites were born in the 1960s and '70s. And 39 percent were born in the '80s and '90s.

Summer is always a peak season for travel. It's estimated that over 30 million users of Ctrip are visiting red tourism sites in China this summer.

"Such change is worthy of attention. It means that more young Chinese are getting to know about the country's history during their travels," says Shao Jihong, senior director of Ctrip's airline business department.

"Young Chinese prefer personalized itineraries, so it's important to enhance their travel experience."

She says red culture such as performances and festivals and dining can attract more young Chinese tourists. Also, scenic areas should adopt new technology, such as virtual reality.

"Red tourism is more diverse than before, and it can be combined with natural scenery, culture and countryside tourism. It's not just about visiting bronze statues, museums and former residences of famous people anymore."

She also adds that in China, many scenic red tourism areas are enhancing their interactivity. For instance, in Shanghai, tourists can role play and take part in escape room games in some scenic spots. And in Chongqing, there are souvenirs related to red tourism.

"China boasts plenty of scenic red tourism sites, with more traveler focused resources being developed in surrounding areas. These destinations are suitable for the patriotic education of young people," she says.
