The Maritime Silk Road refers to the maritime passage for economic and cultural exchanges between ancient China and other parts of the world. The Maritime Silk Road was an international trade network composed of a series of port exports at that time.

The Maritime Silk Road can be traced back to the Han Dynasty. The main reason is that there are few mountain plains along the southern coast of China, and internal communication is not easy. Local governors also need to trade overseas resources to maintain their rule. The southeast coast can use the Xia Dong monsoon to help navigation, which increases the convenience of maritime navigation. So many places along the coast of ancient China had this kind of communication.

During the prosperous period of Tang, Song and Yuan Dynasties, China's Maritime Silk Road was mainly composed of Guangzhou, Quanzhou and Ningbo and other feeder ports. Guangzhou is the only foreign trade port in China that lasted for two thousand years. During the Wei, Jin, Southern and Northern Dynasties, Guangzhou was the port of origin of the Maritime Silk Road. During the Tang and Song Dynasties, Guangzhou gradually became the largest port on the Maritime Silk Road. During the Ming and Qing Dynasties, when the government was closed to the outside world, Guangzhou once became the only foreign trade port in China. From the end of the Song Dynasty to the Yuan Dynasty, Quanzhou became the largest port in China, and was called "the largest port in the world" together with Alexandria. Later, it declined due to the maritime ban in the Ming and Qing Dynasties. The starting point of the Maritime Silk Road recognized by UNESCO was Quanzhou.
