Which is better, Haikou Ferry, xiuying port or Xinhai Port?

Haikou Xingang is good. According to relevant public information, Xinhai Port is close to the urban area, with many flights, large tonnage and relatively fast speed. It is also the only outlying island wharf to buy duty-free goods from outlying islands, close to the largest duty-free city newly built in Hainan. Xiuying port Wharf is located in the urban area. Outside China, except for car ferry, bus ferry and passenger ferry, individual passengers choose xiuying port Wharf. Disadvantages are fewer sea flights, small tonnage and slow speed.
