There are two main views about grain. Mainstream rice (commonly known as rice, rice), millet (commonly known as yellow rice), millet (Jiì, also known as millet, commonly known as millet), wheat (commonly known as wheat for flour) and glutinous rice (commonly known as soybean). Because the dry climate in some places is not conducive to the cultivation of rice, hemp (commonly known as pockmarked) is used instead of rice as one of the five grains.

Millet: Millet is shelled, that is, yellow rice. When cooked, its son becomes sticky and can be used to make wine and cakes. Because it is not conducive to digestion, "millet" is basically not used as a staple food now.

Xiaomi: Also known as Xiaomi, it is drought-tolerant and has many varieties, commonly known as "colorful millet", including white, red, yellow, black, orange, purple millet and sticky millet. The earliest wine in China was also made from millet. Millet is suitable for growing in arid areas without irrigation. Its stems and leaves are hard and can be used as feed. Generally only cows can digest it. The staple food now is basically not "millet".

Hemp: Hemp is mainly used in agricultural production, and its stem bark can be made into rope (hemp rope), hemp clothes, hemp paper and so on after retting, which is very durable. Peeled stems can be used as firewood and build houses, which feels a little woody. At present, skins and stems can be made into various high-grade papers such as Xuan paper by refining fibers.

Zizania latifolia: The general term for beans, and bean products are also one of the favorite foods in China.

The saying of whole grains has a long history. China people's eating habits with whole grains as the main body have been followed for thousands of years. As early as 2,000 years ago, the book Huangdi Neijing put forward that grains should be used as nourishment, five fruits should be used as help, five livestock should be used as benefit, and five vegetables should be used as supplement.

Usually people think that rice and wheat are flour and rice, and miscellaneous grains refer to other grains. What we are talking about now is actually a big family, including many kinds of cereals and beans, such as millet, corn, brown rice, buckwheat, barley, oats, sweet potatoes, black beans, broad beans, mung beans and peas.
