Travel site Tuniu takes on big rivals Ctrip and Qunar

Chinese online travel agency Tuniu is taking on rivals Ctrip and Qunar for a bigger share of the country's online tourism market by expanding its services to flight and hotel bookings.

Over the past 10 years, Nanjing-based Tuniu has focused on providing leisure travel services, which include helping travelers book tickets to tourist sites, local transportation, package tours and itineraries at destinations both in China and abroad.

Online travel agencies like Tuniu have boomed with the growth of China's middle class. According to research firm Analysys, Tuniu was ranked as the second largest online leisure service provider in 2015. The company had a market share of 23.1 percent, slightly lower than the 24.6 percent held by Ctrip, according to Analysys.
