Inland waterway transport is an important part of water transport, which is the link between inland hinterland and coastal areas, and plays an important role in the transport and distribution of import and export goods.
Parcel service is a relatively simple mode of transportation. There are agreements and contracts between the postal departments of various countries. Through these agreements and contracts, postal parcels of various countries can be transmitted, thus forming an international postal parcel transport network. Due to the nature of international multimodal transport and "door-to-door" transport, as well as simple procedures and low costs, international parcel post transport has become one of the transport modes widely used in international trade.
