From the perspective of Taobao stores and WeChat business, it is increasingly difficult to obtain customers. After obtaining customers, it is important to retain customers, which requires providing more varieties of agricultural products covering different seasons in spring, summer, autumn and winter, and correspondingly requiring "one-on-one" partners from different producing areas. Of course, high-quality partners are hard to find, and buyers will encourage sellers to "reward sellers" and maintain long-term cooperation with sellers. The so-called "reward the seller" is to make the seller have more profits and enough enthusiasm. The origin of "one item for one generation" or "one button for one generation" attracts restaurant chains, unit group purchases and independent small and medium-sized supermarkets with its convenience, efficiency and transparency.
