Corn was introduced to China in the16th century, and it was first recorded in Gongxian Annals written in Jiajing thirty-four years of Ming Dynasty, which was called Yumai. Later, in the thirty-ninth year of Jiajing, Pingliang government ruled, which was called Fanmai and Xitianmai. The name "corn" was first seen in Xu Guangqi's "Agricultural Administration". Apart from the United States, China is one of the most popular areas for corn cultivation. Corn is also the tallest grain in the world.

Corn is native to Mexico and Peru at the foot of the Andes in Latin America. It is the main food crop planted by Indians. It used to be a very small grass, and it likes high temperature. Before the big corn appeared, it had been planted by Native Americans for many generations. 1492, Columbus discovered corn in Cuba and planted it in North and South America. After being brought back to Spain in 1494, corn gradually spread all over the world and became one of the most important food crops.
