In 1998, Xi Jinping, who was then the deputy secretary of the provincial party committee, came to Nanping City in southeastern China's Fujian Province to investigate. Farmers there were very eager for agricultural technology, and the "Sci-Tech Expert" system was later born there. On March 22, 2021, Xi Jinping visited Wuyishan, Fujian Province, to clearly and deeply promote the "Sci-Tech Expert" system. Under the care and guidance of Xi Jinping, the "Sci-Tech Expert" system not only solved technical problems and improved farmers' understanding of scientific and technological operations, it also helped farmers to create many new business models.
