Legal analysis: if the circumstances are serious, it constitutes domestic violence. As long as family members use beatings, binding, mutilation, forced restriction of personal freedom or other means, causing physical and mental harm to their family members, it constitutes domestic violence. If the daughter-in-law quarrels with her mother-in-law, she doesn't often beat and scold her mother-in-law. It can't be said that the daughter-in-law has domestic violence against her mother-in-law, but it is definitely illegal to beat her mother-in-law, and it may be detained by the public security if it does not constitute a crime.

Legal basis: Article 22 of the Regulations of the People's Republic of China on Administrative Penalties for Public Security commits one of the following acts of infringing on the personal rights of others, which is not serious enough for criminal punishment, and shall be detained for a maximum of 15 days, fined for a maximum of 200 yuan or given a warning: (1) Beating others, causing minor injuries; (two) illegally restricting the personal freedom of others, or illegally invading other people's homes; (3) publicly insulting others or fabricating facts to slander others; (4) maltreating a family member, and the abused person requests to deal with it; (5) writing threatening letters or threatening the safety of others or interfering with the normal life of others by other means; (6) coercing or tricking people who are under the age of 18 to perform horrible and cruel programs, thus destroying their physical and mental health; (7) Concealing, destroying or opening others' mails and telegrams without permission.
