"Valley" originally refers to grain with shells; Like rice, millet (Ji meter, that is, millet) and millet (also known as yellow rice), there is a shell outside, so it is called valley. The sound of the word Gu comes from the sound of the shell. Grains were originally called five kinds of grains in China in ancient times, and later they generally referred to grain crops.

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