Social security transfer: worked in Luoyang for three years, paid social security for three years and had a social security card, and then worked in Zhengzhou.

You worked in Luoyang for three years, and now you don't work in Luoyang. You can ask the former Luoyang unit to issue a certificate of resignation, then go to Luoyang Social Security Bureau, bring your ID card to go through the formalities of transferring social security to Zhengzhou, and merge it into one account.

In addition, if you have worked in Zhengzhou for one year, if you resign, you can apply for a social security card in the social security area of the former Zhengzhou unit, and then let the current unit transfer to this social security card number.
