tolerable. However, if the mentally ill person is a person without capacity for civil conduct, and the act of divorce by agreement is invalid, the man may file a lawsuit for divorce in the court.
 According to Article 3 of the Supreme People's Court's "Several Specific Opinions on How People's Courts Decide That the Couple's Relationship Has Really Broken", it is deemed that the couple's relationship has really broken if they conceal mental illness before marriage and cannot recover after marriage, or if they know the other party has mental illness before marriage and marry him, or if one party has mental illness during the couple's life together and cannot recover after a long time of treatment, it is deemed that the couple's relationship has really broken. If one party insists on divorce and the mediation fails, the divorce can be granted according to the law.
