China's green and intelligent vessels have reached an international first-class level. On the 18th National Maritime Day, we take a close look at the ships which represent China's innovation in this industry. We climb aboard Yu Kun, the world's most advanced and China's first domestically-designed sailing teaching vessel. We also take you inside China's first LNG-powered intelligent marine patrol ships and the Haixun 06, a large-scale ocean patrol ship that has an automatic engine room. Don't miss the golden chance to take a close look inside these innovative vessels.
