Sea transportation refers to the transportation of people or goods by water and air. Generally speaking, water transportation takes a long time, but the cost is relatively low, which is unmatched by air transportation and land transportation. Water transport can transport a large number of goods per voyage, while air and land transport have relatively few loads per voyage. Therefore, in international trade, waterway transportation is a more common mode of transportation. Since the 15th century, the vigorous development of shipping industry has changed human society and natural landscape.
    In 2020, the country's commercial passenger traffic volume will reach 9.665 billion and passenger turnover will reach 1925.143 billion person kilometers, down 45.1% and 45.5% respectively over the previous year. Among them, 150 million people were transported by waterway and 418 million by civil aviation, down 45.2% and 36.7% respectively over the previous year.
    Regular shipping
    Regular sea transportation refers to that ships accept sporadic groceries or container freight between ports on a fixed route and sail back and forth according to the pre arranged shipping schedule. One of the advantages of regular shipping is that the freight rate is relatively stable.
    Compared with regular shipping, irregular shipping. Irregular shipping is mainly used to transport dry bulk cargo or oil. There is neither a fixed schedule nor a fixed route. Its voyage depends on the needs of cargo flow, which is different from regular shipping.
