What do you mean, patients are decided by lot?

Draw lots for the old, the weak and the sick.

Mental illness is difficult to test by yourself. If you find yourself hearing voices, hallucinations, ghosts and other abnormalities, you should go to the psychiatric department for examination and identification. Mental illness is mainly delusions and hallucinations. For example, I feel that someone is pointing at him, someone is following him, and even wants to hurt him. I often talk to myself and giggle.
