Which grain is the Buddhist grain?
Cereals are called "rice, millet, millet, wheat and glutinous rice" in Mencius Teng Wengong and "barley, wheat, rice, adzuki bean and flax" in Buddhist sacrifices. Then Li Shizhen recorded in Compendium of Materia Medica that there are 33 kinds of cereals and 0/4 kinds of beans. At present, the general "whole grains" refer to rice, wheat, soybeans, corn, potatoes, etc., while grains other than rice and flour are customarily called whole grains, so whole grains also refer to food crops. Therefore, it is generally believed that grain is the general term for food crops.

Second, the origin of whole grains

The earliest record of the word "five grains" can be found in the Analects of Confucius. According to the Analects of Confucius, more than 2,400 years ago, Confucius took his students on a long journey, and Luz fell behind. He met an old farmer with a bamboo basket and a stick, and asked him, "Have you seen Master?" The old farmer said, "Who is the master if you don't work on all fours?"

Grains mean five kinds of grains, but when the word "grains" was first coined, it was not recorded what it meant. There are two main explanations of Han people and their descendants: one is rice, millet, millet, wheat and glutinous rice (that is, soybeans); Another way of saying it is marijuana, millet, millet, wheat and glutinous rice.

Although the concept of five grains has a history of more than two thousand years, the status of these crops in the national food supply has changed from time to time. Millet, millet and other crops in the five grains have the characteristics of drought tolerance, barren tolerance and short growth period, so they occupy a particularly important position in the original cultivation of dry land in the north.

The increase of population in southern China is closely related to rice production. Rice is very suitable for planting in the southern region with abundant rainfall, but at first it was inconspicuous and even excluded from grain. However, it came from behind. After the Tang and Song Dynasties, the status of rice in the national grain supply was increasing. According to the estimation of Ming Dynasty and Song Dynasty, the grain supply at that time was mainly rice, while rice, wheat, millet and other grain crops accounted for only three tenths, which had been relegated to a secondary position. Soybean and hemp have withdrawn from the category of food crops and are only used as vegetables. However, when some crops withdrew from the ranks of food crops, some crops joined the ranks of food crops. At the end of the Ming Dynasty, corn, sweet potato and potato were introduced into China one after another, which became an important part of the main food crops in modern China.
