Sea freight is the slowest method of transport, but if time is not a factor for you then a ship wins every time. And of course, some goods simply cannot go by air due to their size or weight or the fact that they are not permitted on board an aircraft.
海运是最慢的运输方式，但如果您并不在意时间问题，那么这是个很好的选择。 当然，有些货物由于其尺寸或重量或者不允许在飞机上使用而无法通过空运，但可通过海运。
