I bought it at Kangxuanhui, a community group buying platform operated by CommScope Group, which specializes in healthy and nutritious consumer goods, with the aim of caring for health and sharing business. CommScope has its own factory and planting base, with guaranteed product quality, cost performance and market year-on-year. I bought it many times and shared it with friends around me, saying that the quality of Lycium barbarum and Hippophae rhamnoides bought on it is better than that they bought before.
