This type of business is operated by the union. The red tomato real estate coalition is a new business model for housing intermediaries, not an industry. In accordance with the principle of division of labour in the union system, the head office (licensor) is responsible for strategic planning, service development, etc. For the operation of the tomato estate, the provision of a full set of business techniques for the union stores (licensed persons) and the training and continuous advice, investigation and development programmes, as well as the integration of information management and advertising, to help the union stores gain greater access to business.
