Which country is the origin of sweet potatoes
Sweet potatoes are native to the Americas. The first batch of sweet potatoes in Europe was brought back by Columbus in 1492, and then introduced to Africa by the Portuguese, and to Asia by the Pacific Islands. Sweet potatoes were first introduced into China in the Wanli period of the Ming Dynasty, when Chen Zhenlong, an overseas Chinese from Fujian Province, often went to Luzon (now the Philippines) to do business, and found that Luzon produced the highest yield of sweet potatoes, so he patiently learned the cultivation method from local farmers. Later, after the promotion of the Chen family, sweet potatoes were widely planted throughout the country.
