If you have a social security system, you can make a one-time contribution for 15 years. It seems that an old man in Guangzhou, who is more than 90 years old, has made a one-time contribution, but the specific cost and the standard of receiving it are not the same in different provinces and cities.
If it's a farm insurance policy, I haven't heard of a one-time payment yet. As long as it is more than 60 years old farmers, do not have to pay fees, instant enjoyment of old age treatment, just treatment on a few dozen dollars.
If you want to buy commercial pension insurance, there is also an age limit, more than 60 years old, you can not buy, the specific payment standard, according to the family's financial situation, more payment more collar.
