The first step in LDC's sustainable agriculture work is to get closer to the source of food and preserve the surrounding ecological environment. Fleur de Chine Hotel has adopted the "Friendly Farmland" in Dou Nan, Yunlin. It is cultivated without pesticides and chemical fertilizers to ensure farmers' income and encourage more farmers to join the ranks of friendly farming. The ecological environment has also improved, with environmental indicators such as the Crested Ibis and Black Kite appearing one after another. Chefs from the hotel also visit the site to learn about planting and harvesting, as well as maintaining the fields, and then bring the harvested rice back to the hotel's restaurant for guests to taste the healthy flavors.
