Baidu probe

China’s biggest search engine Baidu was put under investigation in May 2016 after the death of a cancer-stricken young man who had opted for treatment sourced online. Wei Zexi, 21, underwent an experimental immunotherapy programme that he had found on top of his Baidu search results. The treatment caused him to lose critical time for cure and he died in April 2016. Baidu charges advertisers for ranking them high in its online searches.
