1. The term "139 months" refers to the number of months used to calculate the pension upon retirement.2. After receiving pension payments for 139 months, the pension amount will not decrease. It simply indicates that the pension account balance has been fully exhausted at the age of 60, and a recalculation will take place.3. Initially, the calculation of the pension payout period was uniformly set at 120 months to address the issue of retirement incentives and to encourage later retirement.4. The number of months for calculating pensions is determined by the retirement age. For example, at 40 years it is 233 months, at 60 years it is 139 months, and at 70 years it is 56 months. This setup simplifies calculations and promotes delayed retirement.5. The payout period is primarily used for pension calculations and does not mean that the pension will be exhausted upon reaching the designated number of months. Pensions are paid lifelong and only cease upon the death of the recipient.6. Once the personal account balance is depleted, the pension will continue to be paid because there is also a component financed by the employer.7. The personal account pension will also earn interest, and any remaining balance in the account can be inherited by the children in the event of the account holder's death.8. As long as the insurance premiums are paid on time, there is no need to worry about the pension amount decreasing or being exhausted. Policies have clear regulations for calculating pensions to ensure retirees receive their pension payments.詳情
