Mobile games are gaining popularity in China, but developers face a multitude of challenges, as Yang Yang reports.

For Yang Zhen, 33, there are only two types of people in the world - those who love computer games and those who don't. Since his early days at college Yang has been a computer game fanatic. He started with the shoot 'em up Red Alert before moving on to the online role-playing game World of Warcraft, where he spent thousands of yuan on equipment and online tools, as well as a large part of every weekend working in collaboration with cyber friends to achieve the ultimate victory.

But in 2013, the appeal of World of Warcraft gradually began to wane. Instead of sitting at his computer terminal after a busy day at work, the engineer at a power company in East China's Zhejiang province preferred to lie on his couch reading online fantasy novels or playing online game adaptations on his smartphone while keeping an eye on his 6-year-old daughter.
