I guess international logistics sales are easy to do, but I'm not sure. It's just a personal guess. Don't take it seriously. It's better to do a field investigation. International logistics, also known as global logistics, refers to an international commodity transaction or exchange activity in which production and consumption are carried out independently in two or more countries to overcome the spatial and temporal distance between production and consumption and to physically move materials, thereby achieving the ultimate goal of international commodity transactions, that is, realizing the trade convection conditions of the seller delivering documents, goods and collecting payment, and the buyer accepting documents, paying payment and collecting goods.
