1. Property protection: The main task of property insurance companies is to provide property protection to protect the property of individuals and enterprises from accidental losses. It can cover various property types such as houses, vehicles and commercial assets, and provide compensation and maintenance services to help the insured recover losses.

2. Risk diversification: Property insurance companies manage risks through risk diversification. Collect insurance premiums from different insured persons and form an insurance fund to pay those who suffer losses. This risk dispersion mechanism can reduce the economic pressure faced by individuals or enterprises due to property losses.

3. Insurance contract: An insurance contract is established between the property insurance company and the insured to clarify the rights and obligations of both parties. The insurance contract stipulates the scope of insurance, the amount of insurance, the way of premium payment and other important terms, which provides legal protection for both parties.
