/kloc-More than 0/6 minors immigrated to Germany.

First of all, do you and your current husband get a license? If you get the certificate, then your current husband is your son's stepfather, that is, Stiefvater.

With the guarantee provided by his stepfather, your son can study and live in the past, but he has to go to Auslaendischer Amt, the German foreigner management office, to go through the relevant formalities every once in a while.

For details, please consult the German Embassy in China.

I hope it helps you.
