What should my son do if he beats his parents? Besides, he is 40 years old.

Suggest calling the police. If the police don't accept it, they can take civil action. According to Article 25 of the Law of the People's Republic of China on the Protection of the Rights and Interests of the Elderly, domestic violence against the elderly is prohibited.

If the perpetrator insults others for many times, he may be required to bear corresponding responsibilities according to the provisions of the Law on Public Security Administration Punishment. Because the Law on Public Security Administration Punishment stipulates that those who publicly insult others or fabricate facts to slander others will be detained and fined according to the seriousness of the case, which means that the actor may bear administrative responsibility. However, the subject of this case is special and the two sides are related. How to solve it, we still have to find out the reasons for the contradiction between parents and children.

If it is because of the problem of providing for the aged, such as the son's failure to support and disrespect his parents. Then both parties can try to focus on negotiation or find relevant personnel to mediate. But if negotiation fails, parents can take up legal weapons to safeguard their legitimate rights and interests.

Because in China, young people have the obligation to support the elderly, the Civil Code stipulates: "Adult children have the obligation to support, help and protect their parents." There is a similar provision in the Law on the Protection of the Rights and Interests of the Elderly: "The supporter shall fulfill the obligations of financial support, life care and spiritual comfort for the elderly and take care of their special needs". In other words, children need to give spiritual comfort to the elderly, in addition to economic supplies.

There are similar cases in judicial practice:

For example, in 2005, 66-year-old Mrs. Meng took her three sons to court for failing to fulfill their maintenance obligations and not paying alimony. After trial by the local people's court, it was decided that the three defendants would pay the alimony of 2,400 yuan to Mrs. Meng every year.

However, if the circumstances are bad, such as children's long-term abuse or abuse of the elderly, then their children do not rule out the possibility of criminal responsibility. It is said that "thinking about the source of drinking water is common sense, and filial piety ranks first in life among all virtues." Filial piety to the elderly is the traditional virtue of the Chinese nation. Our parents gave us life. We should use our own strength to help our parents feel safe and enjoy their old age. There are indeed cases of beating and cursing.
