What should parents do if they send their normal children to a mental hospital because of family conflicts? How do we sue them?

The man above is half right. You can really file a private prosecution. But first of all, you should be able to write a letter of complaint, with a format and standards. If the format is incorrect, the court registry will not accept it. So at this time, you need to hire a lawyer, and the lawyer will tell you what to do without worrying about the lawyer's fee. Last year, the new procedural law stipulated that as long as you win the lawsuit, that is, you win the lawsuit, and all the legal expenses of both parties shall be borne by the losing party. Moreover, whether it is mental illness or not, you can do judicial appraisal. No one has the right to say who is crazy.
