In ancient times, grain was called five grains, and the word "five grains" first appeared in The Analects of Confucius. Huangdi Neijing, a famous ancient book in China, said: "Grains are the nourishment". There is a saying among the people that the grain is abundant. In ancient times, five kinds of grains were called rice (paddy), wheat (wheat), glutinous rice (beans), millet (yellow rice) and millet (millet is millet).

Later, during the Wanli period of the Ming Dynasty, corn and sweet potato were introduced into China from South America and Nanyang respectively. The "five grains" were Fugu, wheat, corn, soybean and millet.

Staple food and miscellaneous grains are collectively referred to as grain. Coarse cereals such as peanuts and sesame seeds that can be used to extract oil are called oilseeds.
