Will social security files check fake academic qualifications?

I can't. The social security system only supports querying social security payment and enrollment time. Education can be queried in China talent official website, but not in the social security system.

Legal objectivity

Article 88 of the Social Insurance Law of People's Republic of China (PRC) defrauds social insurance benefits by fraud, forgery of certification materials or other means, and the social insurance administrative department shall order it to return the defrauded social insurance benefits and impose a fine of more than two times and less than five times the amount defrauded.
