Domestic trade or foreign trade: generally, domestic trade ships have shorter sailing time, convenient berthing, easier serving and fresh vegetables and meat. If it is an ocean-going ship, because of the long sailing time, especially fishing boats, they can't stay for a long time and can only live on frozen food and fish and seafood.
Strength of shipowners: In recent years, shipping has been sluggish, and many shipowners have made corresponding changes in food in order to save costs. In the past, domestic ships were usually four dishes and one soup, of which two were meat and two were vegetarian. Now, basically, the boat owners have changed the food on board to one meat, one vegetable and one soup. Therefore, food is also linked to the economic strength of ship owners.
There is also a foreign ship. The food conditions on foreign ships are much better than those in China. In addition to the main meal, there will be desserts and drinks after meals, which are more comfortable to eat.
