Depends how traditional the family is or what happened in the marriage etc.
My aunt took off from an abusive marriage. Her 2nd husband married her as if she was never married. So the kowtow, the whole marriage song, the average bride price of a new bride, basket blanket carrying etc
Another family, very traditional, requested their new son in law do the whole new wedding process for their lawyer daughter, although she was the one to carry on multiple affairs on her first marriage. It was her title, education and saving face because of her reputible job title. His family was against it but it was his money, he did it anyways. Her bride price was high.
All really depends. Usually 2nd time around, they do a hush hish fast wedding process but the new age generation wants big announcements. If not with hmong wedding, then with meeka wedding for sure.
