Tung-Feng Organic Farmland is sitting in Yilan where is a blessed place. The natural and simple landscape with birds and flowers filling the valley protect people from the hustle and bustle of the city. Although the number of pomelo trees has been less due to zero herbicide and fertiliser, the survivors are even stronger after the selection of natural cultivation. The farmland provides homemade handicrafts and other favourite products, and the soap made from the extracted oil of left pomelo every year and shampoo made from plant oil are available and chemical-free.
