Are there any ships that you can travel to China from America on?

Why the hell would you want to go on a ship to China? Do you know how long it will take?

There are no bus type connections between USA and China. You can either:

A. Book a leg on a cruise ship (many go to China)

or

B. Book a journey and a freighter.

PS: flying is by far cheaper!
