[Legal Opinion]
 If the man suffers from mental illness during the period of the husband and wife's life together and cannot recover after a long time of treatment, it shall be deemed that the relationship between the husband and wife has really broken down. If one party insists on divorce and the mediation fails, the divorce can be granted according to the law.
 [Legal Basis]
 According to the Several Specific Opinions of the Supreme People's Court on How People's Courts Decide that Couple's Feelings Have Really Broken in Hearing Divorce Cases:
 In the trial of divorce cases, the people's court should distinguish whether the couple's feelings have really broken when granting or not granting divorce. To judge whether the relationship between husband and wife has really broken, a comprehensive analysis should be made from such aspects as the basis of marriage, the feelings after marriage, the reasons for divorce, the status quo of the relationship between husband and wife, and whether there is a possibility of reconciliation. According to the relevant provisions of the Marriage Law and the experience of trial practice, in any of the following circumstances, it is deemed that the relationship between husband and wife has indeed broken. If one party insists on divorce and the mediation fails, the divorce can be granted according to the law.
 He/she conceals mental illness before marriage and cannot recover after marriage, or he/she marries because he/she knows that the other party is suffering from mental illness before marriage, or one party suffers from mental illness during the life of the couple and cannot recover after a long time of treatment.
