Which month can't Henan cover with a quilt?

The customs in different parts of Henan are also different.

Generally speaking, you can't open the quilt in May and cover it in July and September. Quilt means to sew, which means to open the quilt in May and keep it in May. Tucking in July and September means giving birth to seven and nine girls.

But this is an ancient custom, which has been reformed now.
