Liu Caihong, a villager from the west of Niujia Zi Ying Village, Niujiayingzi Town, Harqin Banner, came to his own land, dug up the medicinal material Tieqi planted last year, and then dug up the whole land for planting platycodon grandiflorum this year. Liu Caihong's husband said, "Last year, I planted an iron horse. This year, I planted a platycodon grandiflorum. I planted it by turns. Adenophora adenophora is usually sold to Guangzhou, and platycodon grandiflorum is taken away by Bozhou businessmen and then resold to South Korea. Now three Ji Meng pharmaceutical companies in Niuyingzi area have signed contracts with us, which is guaranteed in terms of sales. "
