How to open a childless certificate for the first marriage of a rural hukou man in Liaoyuan? What materials are needed? Thank you.

You'd better go by yourself, but if you can't, you can ask your parents to help you! Go to the family planning office in Liaoyuan to get a sample of the first marriage without children, get an official seal from the village, and then get an official seal from the family planning office! Generally, you need a household registration book and a marriage certificate. A copy of the marriage certificate should also be useful. You'd better ask your family to consult the women's director or the family planning office. I hope my answer can help you.
