Procurement is defined as agent procurement. Popular means to ask someone to help you buy the goods you need. The reason can be that the goods can't be bought locally, and the price of local goods is more expensive than that of other regions, or it can be to save personal time and cost, and ask someone to buy it for you and deliver it to your door. Helping people buy goods from Hongkong, Macau, Taiwan Province Province, and even the United States, Japan, France, and South Korea, and then delivering them by express delivery or directly bringing them back, or taking them abroad from China to others, is a common form of purchasing. There is also a kind of purchasing. Because of the lack of information about the goods consumers want to buy, they can't determine their actual value, and they don't want to be slaughtered by merchants, so they have to entrust an intermediary to help them bargain, or simply let the intermediary buy them on their behalf.
