The era of monopoly of e-commerce giants is gone forever. At the beginning, a treasure started from a small seller at the bottom, and when it developed to a higher level, it gave up the users at the bottom, mistakenly thinking that the people had reached a high standard of living. In fact, the market in third-and fourth-tier cities has not sunk at all. This allowed Huang Zheng in Pinduoduo to find an undeveloped blue ocean, and Huang Zheng made great success by using human weakness (love cheap) and WeChat big data. In the future, I will slowly whitewash my image of selling cheap goods and compete with Ali for high-end customers. E-commerce forms a third trend, which is based on the traditional e-commerce of Ali Big Data, the social e-commerce of Pinduoduo based on WeChat Big Data, and the e-commerce with the advantage of Jingdong Logistics Supply Chain.
