In ancient times, there were two ways to describe grains. One way of saying it is millet, broomcorn millet, rice, wheat, and bean sprouts. According to the records of "Da Dai Li Ji", the five grains are hemp (cannabis), broomcorn millet, millet, wheat, and bean sprouts. The difference between the two versions is that one has rice but no hemp, and the other has hemp but no rice. During the Spring and Autumn Period and the Warring States Period, people's main food was grains. "Grain" originally refers to grains with husks, such as rice and wheat.
