For the suppliers of products, Rosen adopted a strict scoring system, with 80 being the passing line. Only by meeting the standards can we become Rosen's supplier. In addition to food safety, Rosen will regularly check the product quality, clerk service and environmental cleanliness of each store.
At present, Rosen's product quality is supervised by three departments at the same time: Rosen China Investment Company, Shanghai Hualian Rosen Co., Ltd. and the production factory.
