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.

Norman Lamb, chair of the Science and Technology Select Committee, said he plans to convene an evidence session where members of Parliament and Huawei executives will be quizzed on the matter.

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.

Quizzed about the divergence after a speech, European Central Bank President Christine Lagarde noted that after the Russia-Ukraine conflict broke out last year, the outlook was for a euro-area recession - a potentially deep one in some parts.
