Which is more professional, Guangzhou Maritime Exhibition or Dalian Maritime Exhibition?

Personally, I think Guangzhou Maritime Exhibition is more professional. As one of the most important maritime events in China and Asia, Guangzhou International Maritime Trade Fair in China has been successfully held for four times in 2005, 2007, 2008 and 20 10, and has become a remarkable activity center of China and the international maritime community in even years. The exhibition has played a positive role in promoting the communication and development between China and other countries in ship building, marine engineering, ports and shipping industry, and has been fully affirmed and highly praised by people in the industry at home and abroad.
