Is it true that Shanghai recruits sailors?

I have answered many questions like a sailor, so I won't answer the same one. I just want to say that high returns are accompanied by high risks. Sailors are not easy to be, and their lives are in danger at any time. Nowadays, many things happen to seafarers. Imagine why the families of the soldiers in the arms to which the submarine belongs now get the best treatment. In fact, the sea is not easy to mess with.
