How is Baidu's health comment function specifically realized? What if I find malicious bad reviews? Before being installed and used on the bridge, users can log in to comment through their mobile phone number or Baidu account (light comment system), and there is no guarantee that users who comment are all customers who see a doctor. Therefore, it is strongly recommended that you install and use the upper bridge. After the successful installation and use, the previous light evaluation will be cleared. Before the follow-up user evaluation, the hospital needs to check the verification code to confirm that the medical treatment has been completed, or the user uploads the real medical certificate (re-evaluation system). If your re-evaluation still contains malicious bad reviews, you can submit a complaint and provide evidence, which will be judged and handled by the headquarters.
