Harvest season is dry season: Farmers in the village of Butangkou in the province of Jiangxi arrange fruits of the camellia tree (Camellia Oleifera) in a traditional spiral shape for drying. The seeds, which contain a lot of oil, are then extracted from the fruits. Camellia oil is used in Asia in nutrition, as well as a high-quality skin and hair care product. Camellia Oleifera is considered the hardiest species among the camellias.
