How should shipping service companies find business?

the shipping service industry is a very broad industry, including catering, material supply, ship maintenance, shipping agency, shipping agent, crew pick-up and recruitment ......

But which one is it, I think it has something to do with the ship, so I suggest you run more docks, and it is better to get on board when you have the opportunity, so that you can find out where your own advantages are and maximize your own advantages. Wish you success!
