What is a traditional commercial enterprise?

Traditional commercial enterprises are divided into "business" and "business" according to their business models; In ancient times, it was "merchants sitting in Jia", in which "merchants" were generally small-scale mobile vendors; "Jia" refers to a businessman with a fixed shop and firm. The development of modern department stores has changed the general form of traditional commercial enterprises; Large-scale and multi-channel long-distance sales have subverted the original meaning of businesses. However, the traditional mode of businessmen sitting in business has not fundamentally changed. In recent years, the vigorous development of e-commerce has completely subverted the traditional model of commercial enterprises. The traditional commercial enterprises referred to now are actually commercial enterprises with physical stores and warehouses corresponding to e-commerce (virtual stores).
