I would like to know what is the difference between the social security purchased by the nature of the town outside the district and the social security purchased in Guangzhou City?

There is not much difference between the social security of an outlying town and that of a local town in terms of types of insurance and entitlements. If you are an outlying town, you have to receive unemployment insurance and pension in the administrative district where your company is located, while in a local town, you have to receive unemployment insurance and pension in the district where you have your household registration.

The only thing that matters is the maternity insurance you mentioned, but Guangzhou City did not force companies to buy maternity insurance for non-city employees before July 08, so even if you ask the company to buy it for you, you can only buy it from July 08 onwards, but maternity insurance is not counted as one year's worth of maternity insurance, so there is no practical significance in paying for the maternity insurance now, which will only make the company spend more money, and thus attract the company to think of you. The company will not be able to pay the premiums for the insurance, but it will cost the company more money.

Maternity insurance must be bought for a cumulative total of one year in order to enjoy, and the birth and the declaration of the time is still purchased, so you can only ask the company from now on for you to buy, the company refused to do so, you can file a complaint with the labor department to request the intervention of the processing, or simply wait for the birth of a child to directly to the labor department to complain about the maternity insurance, then the company will have to send the wages of the period of maternity leave to you.
