I'm from Xianning, Hubei, and we say there are eighty quilts. One bed should be complete, that is, the quilt cover, pillow and bedspread should be complete. In addition, odd sets of quilts should be prepared, and the number should be even. Usually buy a bed and a baby quilt.
But now many marriages are in different places, so I don't pay much attention to these. It is impossible to notice different customs in two places. Just discuss it with the two families.
