Legal basis:

Article 18 of the Criminal Law of People's Republic of China (PRC) * * * A mental patient who causes harmful results when he is unable to identify or control his own behavior shall not bear criminal responsibility after being identified through legal procedures. However, his family members or guardians should be ordered to take strict care of him, and when medical treatment is needed, it will be compulsory by the government. Intermittent mental patients who commit crimes when they are mentally normal should bear criminal responsibility. If a mental patient who has not completely lost the ability to identify or control his own behavior commits a crime, he shall bear criminal responsibility, but he may be given a lighter or mitigated punishment. A drunken person who commits a crime shall bear criminal responsibility.
