Wei's death led to an investigation by the Cyberspace Administration of China, prompting Chinese regulators to impose new restrictions on Baidu advertisements.
[5][6] State radio operations claimed Wei's family trusted the treatment because it had been "promoted by one of the military hospitals which are considered credible, and the attending doctor had appeared on many mainstream media platforms".
[2][3] Before his death, Wei accused Baidu of promoting false medical information; he also denounced the hospital for claiming high success rates for the treatment.
[3] One later editorial in the People's Daily called Wei's death a "classic" example of the unrealistic "Chinese-style" search for an impossible cure.
Regulators ordered Baidu to attach "eye-catching markers" and disclaimers to advertisements, reduce the amount of promoted results to 30% of the page, and establish better channels for users to complain about their services.
Baidu also planned to create a one billion yuan ($155,038,760 USD) fund to compensate users who suffered demonstrable economic harm from paid results.
