Pinduoduo merchants in remote areas will be restricted by the platform if they don't post, which is the official requirement of Pinduoduo. Because the system has tracking, so if you don't want to be tracked, you have to follow. However, most products on many e-commerce platforms are free of postage. Now almost everyone acquiesces to the mode of free postage for online shopping, but we all know that remote areas do not include postage, such as Tibet, Xinjiang, Inner Mongolia, Qinghai and other provinces. Most of these areas are remote, sparsely populated, with inconvenient transportation and high freight costs. For consumers, postage is definitely better, and to some extent, it is the same for businesses. The sales of postage products will be higher, but some businesses can't afford the cost of postage in remote areas. Setting up some remote areas without postage can save some costs.
