Zhang Qiang died suddenly after suffering from a sudden illness at work. The Bureau of Human Resources and Social Security refused to recognize the work-related injury.

The case was revoked by the court in two instances. Lawyers call for further clarification on the application of brain death standards to the issue of deemed work- related injuries. It can also be seen from the specific process of Zhang Qiang's death despite rescue being ineffective, despite his death being already in a state of brain and his death was irreversible.
