Yantai Salvage Bureau hopes that the senior seamen can give you some answers

First of all, you have to graduate from a prestigious maritime university before you have the opportunity to join a maritime agency such as the Salvage Bureau. From what you say, you should have some connections. I definitely don’t know how much it will cost, and I can’t do it if I know. Say it. . . . Since you have the connection, just ask for the price directly, whatever suits you. I know a person who worked for the Maritime Safety Administration and went sailing to gain qualifications. However, it is required that your position should not be too low. When applying for promotion, you have to go all the way to China, Japan and South Korea. It will definitely not work if it is too far away. The company won't give you much time to upgrade your qualifications, so overall, it's not easy for you to get in. Don't worry about promotion first.
