Shennong's is Yandi, the founder of agriculture in our country. Shennong invented many agricultural tools and household items. He discovered that the seeds of many plants were edible, so he sowed these seeds on the land and kept experimenting. Finally, he found that grains could be planted and harvested year after year, so he chose five kinds of grains from them, namely, Liang, Beans, Wheat, Millet, and Jigen, and taught them to be planted on a large scale to be the main food for people. In the Tang Dynasty, rice was introduced from the ancient city country in the south, and since then it has also become the staple food of the people, and together with the five grains found in Shennong's time, it is known as the "six grains".
