For most public numbers, content realisation is a big problem. Many public numbers will use the form of cooperation with the brand to advertise or to do business in the form of traffic realisation. The premise of cooperation with the brand is that you have at least hundreds of millions of fans or KOL in a vertical field, and unless the brand is directly found, it will be difficult to find cooperation by yourself. Therefore, some public numbers will adopt the form of electricity supplier. There are also two forms of e-commerce, one is self-produced and self-sale (sales of its own brand products, provided that there are products of its own brand), and the other is distribution or distribution (select the products suitable for its own platform). So we will introduce the form of distribution in detail.
