Because insurance goods are different from ordinary goods, the behavior of insurance agencies is only "agency", not "purchase and sale"
The insurance company represents the interests of the insurance company and represents the insurance company in the contract signing.
The same problem can be compared with insurance brokerage companies. The profit of an insurance brokerage company comes from the commission paid by the entrusted policyholder.
Therefore, even if it is a contract signed by an insurance agency and the insured, both parties to the contract are still the insurance company and the insured.
The law prohibits insurance agents from obtaining any benefits other than the contract. So the only source of interest is the commission income paid by the insurance company. Generally it will be indicated in the agency contract.
