My father is an educated youth of Zhushan Brigade, Yang Qing Town, Suixi County, Lianjiang City. 1969. Now he retired at the age of 80. How many years of social security education does he need?

According to the regulations, when your father goes to the countryside, he must go through the "Identification Form of the Working Age of Educated Youth in the Countryside" in the unit, and it will be effective only after it is confirmed and sealed by the unit at or above the county level or the labor department. Without this form, you can't identify the length of service for you. If not, you need to go to the local county archives where your father cut in line, and the copy will be stamped with the seal of the archives, which can prove that any other certificate is invalid.
