Xigua, the video platform of tech giant Beijing Bytedance Technology Co Ltd, disclosed that it will launch its livestreaming quiz from Saturday, which will once again spark a craze like last year, when millions of Chinese played livestreaming quizzes.

Compared with last year, Xigua said that this year's quiz will put more emphasis on knowledge with topics covering a wider range including history, physics and mathematics.

The company said it was "building a way" for people to know if their data was accessed by "This Is Your Digital Life," the psychological-profiling quiz app that researcher Aleksandr Kogan created and paid about 270,000 people to take part in.
