Is it illegal to travel with your girlfriend and share a room at night?

Does not constitute illegal cohabitation.

Illegal cohabitation refers to the behavior that men and women do not live together continuously and stably in the name of husband and wife. According to China's Marriage Law and related laws, illegal cohabitation can be divided into three types: 1. Illegal cohabitation between spouses; 2. Illegal cohabitation between a spouse and a spouse; 3. Illegal cohabitation between spouses. The relationship between real marriage and cohabitation is easily confused, and there are differences between them, mainly in the following aspects: 1, and their constituent elements are different. De facto marriage requires both men and women to live together in the name of husband and wife, and the combination of the two parties meets the legal requirements of marriage. Different from marriage registration, they lack formal requirements, that is, they have not gone through the registration formalities with the relevant administrative departments. And cohabitation has no such requirement. 2. The legal consequences of the two are different. Once it is recognized as a de facto marriage, it will be regarded as a marriage with legal effect and treated equally with a legally registered marriage. Cohabitation is not protected by law, and the property of both men and women during cohabitation cannot be regarded as the same property divided by husband and wife, so the cohabitation relationship should be dissolved according to law. 3. The identity relationship between them is different. In a de facto marriage, both men and women are regarded as husband and wife, and the children born are regarded as legitimate children. It is illegal for a man and a woman to live together. There is no relationship between husband and wife, and the children born are illegitimate children. The property relationship between them is different. In a de facto marriage, the property acquired by both men and women in life is regarded as the property of husband and wife. Unless there is relevant evidence to prove the property obtained during cohabitation, the property under their respective names belongs to them. They have different legal inheritance rights. Couples established in a de facto marriage can inherit from each other according to legal inheritance. Cohabitation men and women do not enjoy the legal right of inheritance. Unless one party makes a will, its inheritance belongs to the other party who lives together. The consolidated appeal states that your actions are only evaluated by the general society, not by the law.
