After seven years' excavation, more than 60,000 porcelain artifacts of the Southern Song Dynasty (1127-1279) have been discovered on Nanhai No.1 ship in Guangdong.

Of the sunken ships discovered in China, Nanhai No.1, a wooden merchant ship of Southern Song Dynasty, is the earliest, largest and best reserved merchant ship for ocean trade, and the only sunken ship which witnessed the Maritime Silk Road in Ancient China. Lying under the sea for over 800 years, the ship was found in 1987 and raised from seabed in 2007.

The "Nanhai No.1" is now exhibited in the Crystal Palace of Guangdong Maritime Silk Road Museum.
