It seems whenever tests are involved, cheating follows. Sure enough, the quiz show phenomenon has led to a proliferation of services and programs that help contestants cheat. CGTN's ZHENG CHUNYING has the story.

A real-life slumdog millionaire. A 23-year-old young lady Xiao Rong from Guang Zhou earned one million yuan after she managed to answer 12 questions correct on a live-streaming quiz app. And there are many more people now in China are dreaming to be another Xiao Rong.

However, with the rising popularity of the live-streaming quiz phenomenon. Businesses selling cheats and tricks have also popped up. Examples include answer databases, voice recognition search programs. They enable users to search for answers on the fly, and plug-ins that analyze search results to give likely answers in a semi-transparent pop-up box, And on e-commerce platform, Taobao, some vendors sell coins to give users a chance to play again.

And with the instant popularity of the show, the competitiveness among live-streaming quiz apps also rises. Many are even burning through money to lure users with bigger and bigger bonuses. But who's offering the prizes behind the scene? The shows have attracted sponsors, bringing in tens of millions of advertising fees to the apps.

"We are planning to spend a huge amount of our budget on investing in such live-streaming platforms, we believe that we can gain profits from the trend."

Needless to say, the investors see expanded possibility for profits for the money they are dropping. However, while internet users are going crazy for the quiz shows, challenges have also arrived, such as the load-carrying capacity of the servers and the sustainability of the user experience. ZHENG CHUNYING, CGTN.
