The agriculture and handicraft industry were very developed in the late Tang and early Song dynasties, which not only satisfied the various taxes of the country, but also met the living needs of farmers. The surplus products were used for trading, which greatly promoted the rapid development of commerce, including the production of Chinese tea. The spread of tea drinking habits has provided a strong material foundation for overseas trade. At the same time, the corresponding science and technology in the Song Dynasty has been greatly developed, and the mileage of commercial ships made in the Song Dynasty can be more lasting, which provides transportation conditions for overseas trade. At that time, the government actively advocated overseas trade, which further stimulated the development of overseas trade in the Song Dynasty.
