First of all, there are two types of ships, one is passenger ship and the other is cargo ship. Passenger ships are generally divided into dozens, passenger ships, cruise ships, and so on. Cargo ships are generally divided into more than 3,000 tons and less, and cargo ships with gross tonnage less than 500 tons are also divided into Class A, Class C and Class D. Now, the development of China's shipping industry is still good. From the downturn of the shipping market in 2008 to the current recovery of shipping, the establishment of the Maritime Silk Road has also promoted the development of the shipping industry to some extent.
