Source of grain declaration:
Grain culture plays an important role and can be described as the origin of human civilization. According to authoritative data, hundreds of thousands of years ago, humans have observed traces of sorghum on stone tools, indicating that grains have been pregnant with humans for more than 100 thousand years. It is a feat in human history to cultivate weeds into coarse grains, which gave birth to human civilization. At the same time, it tells the world that human beings have an indissoluble bond with grains. Grain painting is the highest artistic embodiment and artistic portrayal of grain culture.
The Confucian book "Mencius on Teng Wengong" records that "the tree is full of five grains, and the five grains are ripe to teach people." Zhao Qi, a scholar at the end of the Eastern Han Dynasty, commented: "Five grains, rice, millet, millet, wheat and glutinous rice". The ancients called beans glutinous rice, so the above five crops correspond to today's rice, yellow rice, millet, wheat and soybean respectively.
