1. There is a shortage of seafarers at present. The salary is high, but China seamen can't. I have a friend who works as a three-pipe boat, and his salary is only about 10000 RMB a month, which is far from the international level.

I don't know what you mean by a free sailor. I only know that if you are a sailor in China, you may be far from freedom.

I don't know whether you are talking about employment or internship. Both aspects are linked to schools and enterprises.

4. nothing is wrong. Now the crew is 300% employed. Don't worry about employment, as long as you plan to float on the sea, but you are very tired!

China seamen's schools are better: Dalian Maritime University, Shanghai Maritime University, Jimei University, Guangdong Ocean University (formerly Zhanjiang Ocean University), and Wu Hanyou, whose names I can't remember clearly, seem to be down the river. And China Ocean University. Seafarer's major: navigation technology. Ocean engineering. I don't know the rest.
