In the northeast, it means autumn, which is the harvest season. Plant a millet in spring and harvest 10 thousand seeds in autumn. It means planting corn in spring and autumn. It's great to break it back. We want to rub it into corn kernels, so it means to remove the corn from the northeast, that is, to rub a corn cob into a corn kernel, which means the corn in the northeast.

Rubbing "means rubbing two palms repeatedly, or rubbing them back and forth on something else." "Rubbing corn" means holding the corncob with both hands, rubbing it back and forth and pulling the corn kernels off the corncob. In rural areas, corn stalks are manually transported home from the fields to remove the skins. Some families don't have threshers, so they rub corn by hand. The kneaded corn kernels are bagged and stored.
