Legal analysis: Psychiatric identification is conducted in hospitals designated by the provincial people's government. The diagnostic certificate issued by a mental hospital has legal effect to a certain extent, but it is not the most authoritative. As long as the identification conclusion is that a person is mentally ill, he will be limited to the two categories of "person without capacity for civil conduct" or "person with limited capacity for civil conduct", and there will be no other special categories.

Legal basis: Article 120 of the Criminal Procedure Law of the People's Republic of China. After conducting an appraisal, the appraiser shall write down the appraisal conclusion and sign it. If there is any dispute over the medical appraisal of personal injury and the need for re-evaluation, or the medical appraisal of mental illness, it shall be conducted by a hospital designated by the provincial people's government. After the appraiser conducts the appraisal, he or she shall write down the appraisal conclusion, which shall be signed by the appraiser and stamped by the official seal of the hospital. If an appraiser intentionally makes a false appraisal, he shall bear legal liability.
