Are those people who are hired to go to sea with high salaries really recruited?

Most of it is true. Of course, shell companies or pyramid schemes. Whether the enterprise is a formal enterprise, it is best to consult the relevant local departments. It's hard to go to sea. You may have to stay at sea for several years, and there are unstable risks, climate and other factors, so companies will recruit with high salaries. If you can stand eating fish at sea for a few years, living in a boring and isolated environment, you can try it. There are also supplies for landing at sea. But on the whole, they are at sea all the year round, and the degree of hardship is self-evident. If they can stand it, the salary of sailors is really high.
