Photo introduction: In 1958, Chairman Mao Zedong took a special train for a one-day inspection of Xiangcheng County, Xuchang Prefecture (now Xuchang City), Henan Province. When the chairman saw the large tracts of tobacco leaves growing happily, he said happily: "You have become a kingdom of tobacco leaves!" After that, the reputation of "Tobacco Leaf Kingdom" spread all over the country.
