The shipbuilding in China enjoys a history almost as long as the development of mankind. Through thousands of years, ships have been developed from the raft, canoe, wooden boat, oared boat, wooden sailboat, steamship, and airscrew-propelled vessel to modern steel vessel. The various models, structures, rigs and propelling forces are full embodiment of the diversification in human wisdom and creativity. Among all ships in ancient China, the most famous and influential ones are the towered ship in the Han Dynasty, the grand dragon boat in the Sui Dynasty and Zheng He's treasure boat in the Ming Dynasty.
