Paying social security in Tianjin is said to be more than 2 years in a row, including 2 years?

It is said that paying social security in Tianjin has been going on for more than 2 years, including 2 years. Social insurance in Tianjin needs to be paid continuously for at least one year before applying for insurance registration. If a non-registered family purchases a house in this city, it is necessary to provide proof that it has paid social insurance or personal income tax continuously in this city for more than two years within three years, including two years' payment, and the social security period requires continuous payment without interruption, so the payment is invalid.
