Family to family interaction is to help families improve their viability, while making the family more happy and convenient. Its the value of contacts, not the goal of low price and good quality, but the business civilization of customers, brands, channels, word-of-mouth and emotional interaction. We should break the platform monopoly of technological innovation based on commercial Internet platform, establish a "people + Internet" platform, open up the last mile, restore the essence of business, and build a new ecology characterized by intelligence and Internet innovation. In the process of serving the family, we should inherit the peak value of human service in "family culture", that is, the old and the old, the young and the young, and the weak and the weak.
