What does it mean to put straw on the wedding bed?

The custom of "laying a wedding bed" in Xiangyang countryside has a long history and is very particular.

The night before the groom gets married, the groom's mother will invite two beautiful young women from the neighborhood to decorate the new bed, pillows and so on. This is called a wedding bed.

Although rural people in Xiangyang were poor in the past, they were very particular about laying wedding beds. The wedding bed should be padded with millet straw, and then covered with brand-new quilt cover, sheets and double pillows. Never spread it with straw. It is said that there is barnyard grass in the straw, and the homonym of barnyard grass is "failure"

Why did you choose millet grass as a mattress? The old people in the countryside are old-fashioned, saying that there is grapefruit grass mixed with millet grass. The homonym of this "grapefruit" weed means "having a son". Using millet straw to pave the mattress means that the bride will be pregnant and have a son after entering the door.
