What do real estate agents mainly do?

Conceptually speaking, a real estate agent is an intermediary who engages in intermediary, agency and brokerage business in order to promote other people's transactions in real estate transfer, replacement and leasing activities. Due to the needs of China's national conditions, brokerage business is not allowed for the time being, so real estate agents are mainly intermediaries and agents, while agents generally refer to first-hand housing sales agents, that is, property consultants or sales representatives, and intermediaries are mainly second-hand houses, which are generally called real estate agents in China. That is to say, in China, the concept of real estate agency has been artificially considered as an intermediary institution engaged in the sale and purchase of second-hand houses.
