What's the difference between real estate and property? Don't give me a concept, thank you!

A real estate agent refers to a company that builds real estate. He is responsible for the quality and property rights of the house. Property is the management of community health. Is the house properly decorated? For example, when I need to swipe my electric card at home, I will call the property manager to open the basement door. These miscellaneous things, hehe, just charge property fees. Sometimes developers will have their own properties, and sometimes developers will find another property management community. It's that simple.
