Can the years of non-deep household social security and Xi 'an social security be combined?

If you participate in social security in multiple places, when you reach the legal retirement age, social security will not be automatically merged and you need to take the initiative. This is because the old-age insurance has not achieved national overall planning, but in this case, you can go to the Social Security Bureau to propose social security transfer, and then merge them together for retirement, which means that no matter which province you have paid social security before and how long you have paid social security, there will be a payment record, and social security will be transferred together. Those who meet the retirement conditions can go through retirement procedures.
