The object of legal relationship usually refers to the object directed by legal norms and to which specific subjects exercise rights and obligations. It can be a specific material object or a non-material legal benefit or service. The objects of legal relationships can be mainly divided into the following categories:

1. **Object of property rights**: refers to tangible objects that can be possessed, used, benefited and disposed of, such as land, houses, vehicles, cargo, etc.

2. **Object of creditor's rights**: refers to the payment due due to a contract or other obligation relationship, including currency, delivery of goods, provision of labor services, etc.

3. **Intellectual Property Objects**: Including patent rights, copyrights, trademark rights, etc., which refer to the rights and interests related to intellectual achievements.

4. **Object of inheritance rights**: Involves inheritance, including the decedent’s property and other legally inheritable rights.

5. **Rights and obligations in family law**: For example, the husband and wife share the same property in marriage, the right to support and the right to be supported in the alimony relationship, etc.

6. **Rights and obligations under labor law**: Such as workers' labor remuneration, labor safety, rest and vacation rights, as well as the labor conditions that the employer should provide, etc.

7. **Unowned property**: Property that is not occupied by anyone can become the object of ownership of a specific subject according to legal provisions.

8. **Other non-material interests**: personal rights such as reputation rights, privacy rights, environmental rights, consumer rights, etc.

The objects of legal relationships do not exist in isolation. They are often interrelated with specific legal subjects, legal content, legal form and other elements, and together constitute a complete legal relationship. In specific legal practice, the object of legal relations should comply with the provisions of the law, and should neither be illegal nor exceed the scope given by the law.
