To be precise, there are no ancient poems about potatoes, at least not before the Ming Dynasty. It is difficult to know when potatoes were introduced into China, but the records about potatoes began in the16th century, that is, the Ming Dynasty. Most of the records about potatoes are recorded in some articles, and only Mao Zedong's Nian Nujiao is really written in poetry.
Potato, also known as potato or potato, originated in South America and was introduced to China. Now it is the fourth largest grain crop in the world after wheat.
