Yam is the dried rhizome of the Dioscorea plant in the Dioscoreaceae family. Dig from November to December, cut off the roots, wash the soil, scrape off the outer skin with a bamboo knife, and dry or dry it to obtain hairy yam. Choose coarse Chinese yam, soak it in clean water, add a little heat, and cover it with a cotton quilt to keep it moist and stuffy. Then place it on a wooden board and knead it into a cylindrical shape, cut both ends evenly, dry and polish it, and it is called light Chinese yam.
