Sweet potato is a highly productive and adaptable food crop that is grown in most parts of China. Sweet potato is also known as sweet potato, groundnut, sweet storage, Zhu yam, golden potato, fenzhu, red yam, yucca potato, yam, sweet potato, sweet potato, sweet potato, sweet potatoes, white potatoes, a goose, moe sweet potato and so on. Sweet potato is an annual herbaceous plant, the underground part of which presents a round, oval or fusiform tuber. Native to South America and the Greater and Lesser Antilles, sweet potatoes are widely cultivated in tropical and subtropical regions around the world. Sweet potatoes were first planted in the area of Mexico and Colombia in central America, and were brought to the Philippines by the Spaniards for planting. Sweet potatoes were first imported into China during the Wanli period in the late Ming Dynasty, entering China in three routes from Yunnan, Guangdong, and Fujian, and Chen Zhenlong, a scholar of the Ming Dynasty, was known as the "father of sweet potatoes". During the Wanli period of the Ming Dynasty, a scholar (merchant) named Chen Zhenlong from Fujian Province was doing business in the Philippines when he discovered a crop called "yam" in the local fields, which was not only productive, cultivated independently of the geographical area, but also tasty and filling, so Chen Zhenlong hoped to introduce it to our country, but at that time, the Philippines was under Spanish rule. At that time, the Philippines was under the rule of Spain, and agriculture was better developed. In the name of protecting the species, it was strictly forbidden to bring the potato to other countries for planting. So Chen Zhenlong risked his life by wrapping the potato vines in a rope that was used to tie up the goods, and managed to pass through customs and bring them to our country. Because sweet potatoes are less affected by weather factors and geography than rice and wheat, the crop is now found almost everywhere in the country.
