Let me ask a retarded question. In the concept of civil law, what is the relationship between object, subject matter and subject matter, and what is the difference?

1. The object of civil legal relationship is one of the elements of civil legal relationship, which refers to the object of civil rights and civil obligations as the content of legal relationship. The objects of civil legal relationship include the following categories:

1. Things. These include money and securities.

2. Other properties. Property is a multi-meaning concept in civil law, sometimes it refers to things, sometimes to things and property rights, and sometimes to things and property rights and obligations. Property here refers to property other than things.

3. Behavior. Behavior refers to people's work and service. Such as the custody behavior of the custody items, performance services, etc.

4. knowledge products. Knowledge products are the fruits created by intellectual labor, such as trademarks, patents, technical secrets and discoveries.

5. Personal interests
