Dingyuan Social Security Bureau I am a state-owned enterprise. Is retirement based on the bottom of the unit or the age of the ID card?

The definition of the date of birth when a party retires should be based on the earliest date of birth recorded in his personal personnel file, but not on other materials and ID records kept by the employer.

Notice of the Ministry of Labor and Social Security [1999] No.8 on Stopping and Correcting Issues Related to Handling Early Retirement of Enterprise Employees in Violation of State Regulations

..... The identification of the birth time of employees shall be based on the combination of resident identity cards and employee files. If my ID card is inconsistent with the date of birth recorded in the file, the first date of birth recorded in my file shall prevail. It is necessary to strengthen the management of resident identity cards and employee files, and it is strictly forbidden to arbitrarily change the birth time of employees and fabricate files.
