Is retirement based on length of service or years of social security payment?

According to the social security payment period, the specific calculation method is as follows:

1. Statutory retirement age: 60 for men and 50 for women (55 for women in some management and technical positions).

2. Cumulative payment period: you need to pay a certain social security premium period when you retire, that is, 180 months (15 years). In other words, you can apply for retirement as long as you reach retirement age and the accumulated payment period reaches 180 months.

3. Extension of payment: When reaching retirement age, if the accumulated payment period is less than 15 years, the payment can be extended to 15 years.
