If you want to go to the ship, if you want to be a hull major, I suggest you read more books:

Materials mechanics, engineering mechanics, ship structure, ship design manual, ship structure mechanics, ship statics, ship structure design and other books.

If you want to study marine engineering, I suggest you read the following books.

Ship power system, ship power system and design, engineering thermodynamics, ship transmission and reasoning system, ship air conditioning control system. Handbook of marine engineering design, power and resistance, etc.

If you graduate from a famous university, you have a great chance to enter Dalian Shipyard!

In fact, it is ok to suggest that you learn your major well, because everything you go in has to be re-studied, and it is useless to study in college. After you work, you will find that these four years in college are a waste of time and you can't learn anything useful at all, so this is the main and fundamental reason why it is particularly difficult for freshmen to find a job.

I hope it will help LZ!
